Problem 3 Suppose we sample an analog signal using a sampling rate of fs= 240 HZ. Let us use an intuitive, graphical approach to design a simple, discrete-time filter to

try to remove 60 Hz noise. Use the smallest filter order that makes sense. Show the pole-zero diagram for the filter and the transfer function, H(2). Plot of the magnitude and phase response of the DTFT.
