A digital low-pass filter is required to meet the following specifications: Passband ripple: 1 dB Passband edge:
Question:
Passband ripple: ≤ 1 dB
Passband edge: 4 kHz
Stopband attenuation: ≥ 40 dB
Stopband edge: 6 kHz
Sample rate: 24 kHz
The filter is to be designed by performing a bilinear transformation on an analog system function. Determine what order Butterworth, Chebyshev, and elliptic analog design must be used to meet the specifications in the digital implementation.
