Homework Answers
1. Emitter resistance RE reduce the gain of the amplifier but when we connect emitter by pass capacitor CE parallel to the emitter resistance then the gain of the amplifier is increased. And also it provide the low reactance path to the AC signal. If we remove the emitter bypass capacitor then the extreme degradation is done and it reduce the gain of the amplifier. So it reduce the output voltage.
2. At mid band frequancy the voltage gain is constant. So the transistor parameters(h parameters) are effect the voltage gain at the mid band frequency.
