Microwave Engineering
Microwave engineering pertains to the study and design of microwave circuits, components, and systems. Fundamental principles are applied to analysis, design and measurement techniques in this field. The short wavelengths involved distinguish this discipline from electronic engineering. This is because there are different interactions with circuits, transmissions and propagation characteristics at microwave frequencies. Some theories and devices that pertain to this field are antennas, radar, transmission lines, space based systems (remote sensing), measurements, microwave radiation hazards and safety measures. During World War II, microwave engineering played a significant role in developing radar that could accurately locate enemy ships and planes with a focused beam of EM radiation. The foundations of this discipline are found in Maxwell's equations and the work of Heinrich Hertz, William Thomson's waveguide theory, J.C. Bose, the klystron from Russel and Varian Bross, as w ...

A12 Scale
A12 () is a non- octave-repeating scale or musical tuning featuring twelve steps to the tritave. As twelve steps to the octave is based on a triad of harmonics 4:5:6 (root, major third, perfect fifth), A12 is based on a triad of harmonics 4:7:10 (root, harmonic seventh, and compound major third). Discovered by Heinz Bohlen between 1972 and 1973, it was named "A12" by Enrique Moreno. Cited i"Other Unusual Scales" ''The Bohlen–Pierce Site''. Bohlen considered this scale less logically consistent than the Bohlen–Pierce scale, which has thirteen steps in the twelfth.

Musical Tuning
In music, there are two common meanings for tuning: * #Tuning practice, Tuning practice, the act of tuning an instrument or voice. * #Tuning systems, Tuning systems, the various systems of Pitch (music), pitches used to tune an instrument, and their theoretical bases. Tuning practice Tuning is the process of adjusting the pitch of one or many tones from musical instruments to establish typical intervals between these tones. Tuning is usually based on a fixed reference, such as A440 (pitch standard), A = 440 Hz. The term "''out of tune''" refers to a pitch/tone that is either too high (Sharp (music), sharp) or too low (Flat (music), flat) in relation to a given reference pitch. While an instrument might be in tune relative to its own range of notes, it may not be considered 'in tune' if it does not match the chosen reference pitch. Some instruments become 'out of tune' with temperature, humidity, damage, or simply time, and must be readjusted or repaired. Different method ...

Equal Temperament
An equal temperament is a musical temperament or Musical tuning#Tuning systems, tuning system that approximates Just intonation, just intervals by dividing an octave (or other interval) into steps such that the ratio of the frequency, frequencies of any adjacent pair of notes is the same. This system yields Pitch (music), pitch steps perceived as equal in size, due to the logarithmic changes in pitch frequency. In classical music and Western music in general, the most common tuning system since the 18th century has been 12 equal temperament (also known as ''12 tone equal temperament'', ' or ', informally abbreviated as ''12 equal''), which divides the octave into 12 parts, all of which are equal on a logarithmic scale, with a ratio equal to the twelfth root of two, 12th root of 2, (\sqrt[12] ≈ 1.05946). That resulting smallest interval, the width of an octave, is called a semitone or half step. In Western world, Western countries the term ''equal temperamen ...

Hochschule Für Musik Und Theater Hamburg
The Hochschule für Musik und Theater Hamburg is one of the larger College or university school of music, universities of music in Germany. It was founded in 1950 as ''Staatliche Hochschule für Musik'' (Public college of music) on the base of the former private acting school of Annemarie Marks-Rocke and Eduard Marks. Courses cover various musical genres, including church music, jazz, pop, composition, conducting, instrumental music as well as voice. The theatre academy offers courses in drama and opera and directing in these fields. A third academy offers scientific and educational degrees and qualifications (musicology, music education and therapy). The university is located in the prestigious Budge-Palais in Hamburg Rotherbaum at the Außenalster, close to the city centre.

833 Cents Scale
The 833 cents scale is a musical tuning and scale (music), scale proposed by Heinz Bohlen based on combination tones, an interval (music), interval of 833.09 cent (music), cents, and, coincidentally, the Fibonacci number, Fibonacci sequence.Bohlen, Heinz (last updated 2012).An 833 Cents Scale: An experiment on harmony, ''Huygens-Fokker.org''. The golden ratio is \varphi = \frac = 1.6180339887\ldots, which as a musical interval is 833.09 cents (). In the 833 cents scale this interval is taken as an alternative to the octave as the interval of octave-repeating scale, repetition,833 Cent Golden Scale (Bohlen) , ''Xenharmonic Wiki''. however the golden ratio is not regarded as an equivalence class (music), equivalent interval (notes 833.09 cents apart are not "the same" in the 833 cents scale the way notes 1200 cents ...

Kees Van Prooijen
Kees (Cornelis) van Prooijen (born 7 August 1952) is a creator of computer art. Although it does not bear his name, he independently discovered the Bohlen-Pierce scale, a non- octave-repeating scale based on the tritave and spectra containing odd harmonics, in 1978. Van Prooijen came across the scale through an investigation of continued fractions.Schroeder, Manfred.Music and Mathematics, p.14. ''Nova Acta Leopoldina'' N.F. 92, Nr. 341, (Halle, 2005), pp. 9–15. He also invented the Kees height, or an "expressibility" measure for complexity of just intonation pitch class In music, a pitch class (p.c. or pc) is a set of all pitches that are a whole number of octaves apart; for example, the pitch class C consists of the Cs in all octaves.

Telecommunications Engineering
Telecommunications engineering is a subfield of electronics engineering which seeks to design and devise systems of communication at a distance. The work ranges from basic circuit design to strategic mass developments. A telecommunication engineer is responsible for designing and overseeing the installation of telecommunications equipment and facilities, such as complex electronic switching system, and other plain old telephone service facilities, optical fiber cabling, IP networks, and microwave transmission systems. Telecommunications engineering also overlaps with broadcast engineering. Telecommunication is a diverse field of engineering connected to electronic, civil and systems engineering. Ultimately, telecom engineers are responsible for providing high-speed data transmission services. They use a variety of equipment and transport media to design the telecom network infrastructure; the most common media used by wired telecommunications today are twisted pair, co ...

John R
John R. (born John Richbourg, August 20, 1910 – February 15, 1986) was an American radio disc jockey who attained fame in the 1950s and 1960s for playing rhythm and blues music on Nashville radio station WLAC. He was also a notable record producer and artist manager. Richbourg was arguably the most popular and charismatic of the four announcers at WLAC who showcased popular African-American music in nightly programs from the late 1940s to the early 1970s. (The other three were Gene Nobles, Herman Grizzard, and Bill "Hoss" Allen.) Later rock music disc jockeys, such as Alan Freed and Wolfman Jack, mimicked Richbourg's practice of using speech that simulated African-American street language of the mid-twentieth century. Richbourg's highly stylized approach to on-air presentation of both music and advertising earned him popularity, but it also created identity confusion. Because Richbourg and fellow disc jockey Allen used African-American speech patterns, many listeners thought t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bohlen–Pierce Scale
The Bohlen–Pierce scale (BP scale) is a musical musical tuning, tuning and scale (music), scale, first described in the 1970s, that offers an alternative to the octave-repeating scales typical in Classical music, Western and other musics, specifically the equal temperament, equal-tempered diatonic scale. The interval 3:1 (often called by a new name, ''tritave'') serves as the fundamental harmonic ratio, replacing the diatonic scale's 2:1 (the octave) with a perfect twelfth (an octave higher than a perfect fifth). For any pitch that is part of the BP scale, all pitches one or more tritaves higher or lower are part of the system as well, and are considered equivalent. The BP scale divides the tritave into 13 steps, either Equal temperament, equal tempered (the most popular form), or in a Just intonation, justly tuned version. Compared with octave-repeating scales, the BP scale's interval (music), intervals are more consonance and dissonance, consonant with certain types of acous ...
