Problem 01: An RF engineer needs to use a Butterworth filter to pass an audio signal based on its application. Design the required second-stage Butterworth filter to pass the output signal based on cut-off frequency to avoid the noisy signal with proper labelling, calculation, and explanation. Consider cut-off frequency fc = 55 kHz, quality factor, Q = 5 and capacitance, C = 0.030 µF for the filter. Show the frequency response curve of the constructed filter. Also draw the circuit. The criteria for cut-off frequency, fc, is provided below according to your ID: 5 0 or 2 or 4 or 6 or 8 1 or 3 or 5 or 7 or 9 Pass output signal Before fc After fc [10]
