Biphase or Bi-phase may refer to: *

Biphase modulation Phase-shift keying (PSK) is a digital modulation process which conveys data by changing (modulating) the phase of a constant frequency carrier wave. The modulation is accomplished by varying the sine and cosine inputs at a precise time. It ...

Harvard biphase Harvard biphase is a magnetic run length code for encoding magnetic tape. It is one of the formats employed in forming the digital bits of logic one and logic zero, along with non-return-to-zero (NRZ) and bipolar-return-to-zero (RZ) formats. Eac ...
