Multiplication by n in the discrete time domain corresponds to: differentiating with respect to z and division by -z in the z domain. integrating with respect to z and division by -z in the z domain. differentiating with respect to z and multiplication by -z in the z domain. integrating with respect to z and division by -z in the z domain. Consider the pole-zero plot of a filter as given below. This filter is: stable. unstable. marginally stable. stable for all z domain poles z > 1. Which of the following difference equations represent an FIR (non-recursive) filter? y[n] + 2y[n - 2] = x[n] + 2x[n - 2] x[n] = -y[n] + x[n - 1] - y[n - 3] y[n] = x[n] + 2x[n - 1] + x[n - 2] y[n] = x[n] + 2y[n - 1} + x[n - 1] A Bode Plot corresponds to a straight-line approximation of: an impulse response. a frequency response. a step response. a transient response.Explanation / Answer
