Question: Design an interpolator that increase the input sampling rate by a factor of I = 2. Use the Remez algorithm to determine the coefficients of

Design an interpolator that increase the input sampling rate by a factor of I = 2. Use the Remez algorithm to determine the coefficients of the FIR filter that has a 0.1 – dB ripple in the passband (0 ≤ ω ≤ π/2) and is down by at least 30 dB in the stopband. Also, determine the corresponding polyphase filter structure for implementing the interpolator.
