Prelab 1. Approximation (a) Find the lowest possible f0and check if the filter meets the spec at 32 kHz and 180 kHZ. (b) From the figure, we see that a 1dB peak occurs when damping factor is 0.522 . z=0.1:.001:0.70;hsquared=1./(4*z.^2.*(1-z.^2));hdb=10*log10(hsquared);plot(z,hdb,'LineWidth',3)xlabel('Damping Factor \zeta')ylabel('Magnitude |H(f)| (dB)')title(['|H(f)| vs \zeta, '])grid on
