TEST BANK FOR Fundamentals of Digital Signal Processing Using MATLAB 2nd Edition By Robert J. Schilling and Sandra L. Harris

1.1 Suppose the input to an amplifier is xa(t) = sin(2F0t) and the steady-state output is ya(t) = 100 sin(2F0t + 1) − 2 sin(4F0t + 2) + cos(6F0t + 3) (a) Is the amplifier a linear system or is it a nonlinear system? (b) What is the gain of the amplifier? (c) Find the average power of the output signal. (d) What is the total harmonic distortion of the amplifier? Solution (a) The amplifier is nonlinear because the steady-state output contains harmonics. (b) From (1.1.2), the ampli...
