Unformatted text preview: a. Based on the results from 2, should we place the low-pass filter before the high-pass filter, or should we place the high-pass filter before the low-pass filter? Explain why. b. For the given filter combination, calculate the Loading term between the two filters. Have your result in the form: c. Use matlab to plot the frequency response of your band-pass filter i. Plot the bode plot of the frequency response, G i (jω), for the ideal case with L(jω) = 1, ie, , where G lp is the frequency response of the low-pass filter and G hp is the frequency response of the high-pass filter. (Hint, matlab can do the multiplication of transfer functions for you). ii. Plot the bode plot of the frequency response, G a (jω), for the actual case with the L(jω) you calculated in 3b, ie, iii. Compare the ideal and actual frequency responses of the band-pass filter. Is it a safe assumption to have the loading term approximately equal one?...
