1. What is the decibel voltage gain of an amplifier if it has an ordinary voltage gain of 100,000?
2. The data sheet of an LM380, an audio power amplifier, gives a decibel voltage gain of 34 dB. Convert this to ordinary voltage gain.
3. A two-stage amplifier has these stage gains: Av1 = 25.8 and Av2 = 117. What is the decibel voltage gain of each stage? The total decibel voltage gain?
