2. By applying Bode plot approximations, sketch the response of each filter, and hence complete the Table below. Filter Type Order Cut-off Frequency High Passsecond 120kHz Low Pass fourth 2250Hz 400H...
Figure 2 below shows a bode-plot of a Butterworth response filter, with cut-off frequency, fc of 95 kHz and damping factor, a of 1. Define roll-off rate and explain how it effects the frequency response of this filter. Then, modify the frequency response to have a -80 dB/decade roll-off rate by redesigning the filter with appropriate structure and components value. Draw your filter design. Gain (normalized to 1) OdB -3 dB Actual response of a single-pole RC filter – Passband...
