Consider the example given in textbook pages 91-92. Figure 1 (on page 92) part (d) shows the low pass filtered signal when only the first four harmonic terms are passed through the filter. The low pass filter rejects the other higher frequency components. a) (7 points) compute the percentage of power for the signal shown in part (d) relative to the original signal shown in part (a) of the figure. c) (3 points) compute the bandwidth of the signal shown in part (d) of the figure. Assume A = 2 volts and T = 1 msec.
