Unformatted text preview: a. Based on the results from 2, should we place the lowpass filter before the highpass filter, or should we place the highpass filter before the lowpass 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 bandpass filter i. Plot the bode plot of the frequency response, G i (j), for the ideal case with L(j) = 1, ie, , where G lp is the frequency response of the lowpass filter and G hp is the frequency response of the highpass filter. (Hint, matlab can do the multiplication of transfer functions for you). ii. Plot the bode plot of the frequency response, G a (j), for the actual case with the L(j) you calculated in 3b, ie, iii. Compare the ideal and actual frequency responses of the bandpass filter. Is it a safe assumption to have the loading term approximately equal one?...
