I am trying to impelement FIR compilers in my system design.
I depended on TFilter (http://t-filter.engineerjs.com/) in my design for the FIR filter. The filter parameters (frequency response) are shown in the first attached picture.
The interface connections between the DDS compiler (16 kHz oscillator) the FIR compiler are shown the second attached picture.
After I imported the coefficients file in FIR IP core, then I run the a simulation to check the output of the FIR filter. The third attached picture shows a noisy output for this filter !
The FIR filter type is "Single Rate", the fourth attached picture shows the frequency response for the imported coefficients inside the FIR compiler.
Plz, how to fix the output signal to become smooth like the input?
