(Electrical eng.)
a. Write, compile, and run a C++ program that calculates and displays the voltage gain of a three-stage amplifier at a frequency of 1000 Hz. The voltage gains of the stages are as follows:
Stage 1 gain: 23 / [2.32 + (0.044f)2]1/2
Stage 2 gain: 12 / [6.72 + (0.34f)2]1/2
Stage 3 gain: 17 / [1.92 + (0.45f)2]1/2
f is the frequency in Hz. The voltage gain of the amplifier is the product of the gains of each stage.
b. Redo Exercise a, assuming the frequency will be entered when the program runs.
