In electronics, faithful amplification is the amplification of a signal, particularly a weak one, by a triode or a transistor such that the signal changes in amplitude but not in shape.[1][2][3] In order to achieve this with a bipolar transistor, the transistor is biased.[1][3] Faithful amplification can only occur on transistors with a forward biased emitter-base junction, a reverse biased collector-base junction, and proper zero signal collector current. Without the correct bias, the transistor will not operate efficiently and cause its output to distort.
