## void FIRhighpass_filter | ## (const EST_Wave &sigin, EST_Wave &out_sig, int freq, int order=DEFAULT_FILTER_ORDER)

> Quick function for one-off high pass filtering.

## Documentation

> Quick function for one-off high pass filtering. If repeated highpass filtering is needed, first design the required filter using design_highpass_filter, and then use FIRfilter to do the actual filtering.

Parameters:
  in_sig - input waveform
  out_sig - output waveform
  - freq cutoff frequency in Hertz
  order - number of filter coefficients, eg. 99
