Clipping when using fir_highpass #103

Closed HuongNV96 closed 4 years ago

HuongNV96 commented 4 years ago

Hi all, My code : univector<fbase, 127> taps127; expression_pointer kaiser = to_pointer(window_kaiser(taps127.size(), 3.0)); fir_highpass(taps127, fc/fs, kaiser, true); filter_fir<fbase, fbase> fir_h(taps127); and apply : fir_h.apply(input_h,input); However , input_h signal clipping , when input_h result /= 500 , clipping isn't happen.

Can you help me to solve my issue ?
