frequency
Frequency is the number of occurrences of a repeating event per unit of time. Frequency is an important parameter used in science and engineering to specify the rate of oscillatory and vibratory phenomena, such as mechanical vibrations, audio ...
at which the common base DC current gain
drops to 0.707 of its low frequency value. The common base DC current gain is the ratio of a
transistor's collector current to the transistor's
emitter current, or
