mid band gain of common CE amplifier
Often, it is not the gain AV(dB) that is investigated but rather a normalized ratio AV/AV,mid(dB)=20log(AV/AV,mid). Where AV,mid is called the midrange gain and represents the maximum gain of the amplifier in its frequency working range, for example 20 Hz – 20 kHz for an audio amplifier.
