Multistage Transistor Amplifiers

It is a simple unit Calculations become easy Human ear response is logarithmic None of the above There is considerable power loss There is hum in the output Electrical size of coupling capacitor becomes very large None of the above 3 db 66 db 20 db 200 db 5 db 2 db 10 db 3 db Changes in temperature cause thermal instability Circuit becomes heavy and costly It becomes difficult to bias the circuit None of the above Due to large value of coupling capacitor Low efficiency Large number of components Due to is frequency response Good impedance matching Economy High efficiency Frequency response 600db 24db 14db 31db Voltage Current Power None of the above One stage Two stages Three stages More than one stages Changes abruptly with frequency Is constant Changes uniformly with frequency None of the above Amplifier level output is kept constant Amplifier frequency is held constant Generator frequency is held constant Generator output level is held constant
