WebThe Discrete FIR Filter block independently filters each channel of the input signal with the specified digital FIR filter. The block can implement static filters with fixed coefficients, and time-varying filters with coefficients that change over time. You can tune the coefficients of a static filter during simulation. WebConvert to Fixed Point FIR Filter For the greatest DSP efficiency, the conversion to fixed point must consider the DSP slice’s bus width dimensions, i.e., 27x18-bit multiplier and 48-bit accumulator. Further reducing these bus widths to the very minimum allowable within the design gives the biggest return in terms of resource and power savings.

WebA fixed-point filter uses fixed-point arithmetic and is represented by an equation with fixed-point coefficients.
