Question

Example 1.5 : An amplifier with open loop voltage gain of 1000 delivers 10 W of power output at 10 % second harmonic distortion when i/p is 10 mV. If 40 dB negative feedback is applied and output power is to remain at 10 W, determine required input signal Vs and second harmonic distortion with feedback.

Step 1

The output power Pout is given by the formula Pout = Vout^2 / R, where R is the load resistance. We don't know R, but we can still express Vout in terms of Pout and R: Vout = sqrt(Pout * R). Show more…
