(Text problem 11.7) Design an interpolator that increases the sampling rate by a factor of I = 2. Use an equiripple (Parks-McClellan) filter design to determine the coefficients of the FIR filter that has a 0.1-dB ripple in the passband (0 ≤ w ≤ 0.48π) and is down by at least 30 dB in the stopband (0.5 ≤ w ≤ π). Also determine the corresponding polyphase filter structure for implementing the interpolator.
