Evaluate the voltage gain, Electrical Engineering

Assignment Help:

Q. On a CD amplifier Rs = 4k?, µ =50 and r =35k?. Evaluate the voltage gain Av.

Av = Vo/Vi = µRs / (µ+1)Rs + r
                                 
                                           =  50×4×10^3 / ((50+1)×4×10^3) + (35×10^3)

                                           = 0.836

The positive value indicates that the voltages Vo and Vi are in phase and further note that Av < 1, for CD amplifier.
