Voltage gain of 1,00,000 is equivalent to __________(a) 10dB(b) 1000dB(c) 100dB(d) 50dBThe question was asked by my school teacher while I was bunking the class.I want to ask this question from General Frequency Consideration in chapter Transistor Biasing and Low Frequencies of Analog Circuits

Answer» RIGHT choice is (C) 100dB

Easy explanation: dB = 20 log(VOLTAGE gain)

 Therefor 100000 voltage gain is EQUIVALENT to
