Figure 25: The total frequency response due to CIC and C-FIR frequency response. CIC parameters: input sample = 122.88 MSPS, output sample rate = 960 kSPS, decimation factor (R) = 128, number of stages (N) = 10, differential delay (M) = 1. C-FIR parameters: input and output sample rate = 960 kSPS, number of coefficients = 21, cutoff frequency = 90 kHz, stopband attenuation = 10 dB. |
