This design example uses the InterpolatingFIR block to build a 16-channel interpolate by 2, symmetrical, 49-tap FIR filter with a target system clock frequency of 240 MHz. This design example implements an interpolating CIC filter. This design example implements a full-rate floating-point IIR filter. This design example implements a full-rate fixed-point IIR filter. This design example implements a half band interpolating FIR filter. This design example implements a fractional rate FIR filter.
This design example uses a chain of InterpolatingFIR and DecimatingFIR blocks to build a 16-channel fractional rate filter with a target system clock frequency of 360 MHz. This design example is a multichannel single-rate FIR filter with rewritable coefficients. This design example implements a decimating FIR filter. This design example implements a decimating CIC filter. The resource efficient implementation (three real multipliers per complex multiply) maps optimally onto Intel Arria 10 DSP blocks, using the scan and cascade modes.
