Problem 8 (30 points): Below is a general algorithm for plotting the magnitude response of a filter: Generate a 1 Hz input signal for a large number of samples. Pass it through the filter and obtain the output. Compute the ratio of the "rms value of the output sequence" and the "rms value of the input sequence". This ratio is the magnitude response of the filter at 1 Hz. Repeat this process for 2 Hz, 3 Hz, etc. Plot the magnitude response (in Y-axis) vs. frequency (in X-axis using a log scale). An N-sample moving average FIR filter is given by, y n = 1 x n − i −1 i=0 , an IIR filter with smoothing parameter, , is given by, y n = 1 − x n + y n − 1 , and a difference filter is given by, y n = x n − x n − 1

Apump is used to circulate hot water in a home heating system. water enters the well-insulated pump operating at steady state at a rate of 0.42 gal/min. the inlet pressure and temperature are 14.7 lbf/in.2, and 180°f, respectively; at the exit the pressure is 60 lbf/in.2 the pump requires 1/15 hp of power input. water can be modeled as an incompressible substance with constant density of 60.58 lb/ft3 and constant specific heat of 1 btu/lb or. neglecting kinetic and potential energy effects, determine the temperature change, in °r, as the water flows through the pump.
