An amplifier has an open-circuit gain of-60, an input resistance of 8 k Ω, and an output resistance of 2 k Ω. A microphone transducer source is connected to the amplifier Input and has a source output resistance of 2 k Ω, and a speaker load is connected at the amplifier outputs having a resistance of 10 k Ω. Determine the following
a. Draw an equivalent circuit model showing the amplifier, source and load.
b.Calculate the loaded voltage gain between the source open-circuit voltage and the amplifier output.
