Design a sample-rate converter that reduces the sampling rate by a factor 2/5. Use the Remez algorithm to determine the coefficients of the FIR filter that has a 0.1-dB ripple in the passband and is down by at least 30 dB in the stopband. Specify the sets of time-variant coefficients g(n, m) and the corresponding coefficients in the polyphase filter realization of the sample of the sample-rate converter.
