An amplifier has a power gain of 3db and an input signal


An amplifier has a power gain of 3dB and an input signal power P(In) = 100mW. What is the output power level?

A tank circuit coil is operating at a resonance frequency f(res) = 20 MHZ; The circuit must operate with a bandwith of 200 KHZ. What is the quality factor, Q, for the coil?

 An amplfier has an input signal power P(In) = 500 microfaradW. The output power P(out) = 200mW. What is the gain in dB for the amplifier at that frequency?
