Design a decimator that downsamples an input signal x(n) by a factor D = 5. Use the Remez algorithm to determine the coefficients of the FIR filter that has 0.1-dB ripple in the passband {0 ≤ ω ≤ π/5} and is down by at least 30 dB in the stopband. Also determine the corresponding polyphase filter structure for implementing the decimator.
