1. For a non-linear amplifier with two input frequencies, 3kHz and 8kHz, determine a. First three harmonics present in the output for each input frequency. b. Cross-product frequencies produced for values of m and n of 1 and 2.

this is CC(common collecter ) amplifier.why it is a cc circuit, you can get the answer from its AC circuit.so now PLS draw its AC and DC circuit. plz solve it early

Please help with two questions. What is the cutoff frequency for this amplifier (in kHz)? For input frequency 20 kHz, what is the phase angle (in degrees)?

Consider an amplifier of this output-input characteristics: Vo = C₁ V₁ + C₂ V2 + ...... Assume these inputs: fA(t) = a cos wдt fB(t) = b cos WBt Also assume: C₁ = 0 Cn for n > 3 Find the following: a. The level of the 2nd & 3rd harmonics relative to the fundamental if only one input is used. b. Repeat if the sum of two inputs is used. c. Repeat if the difference of two inputs is used. For b & c the amplitudes of both inputs are the same.
