paz_to_freq_resp(poles, zeros, scale_fac, t_samp, nfft, freq=False)[source]

Convert Poles and Zeros (PAZ) to frequency response. The output contains the frequency zero which is the offset of the trace.

  • poles (list of complex) The poles of the transfer function
  • zeros (list of complex) The zeros of the transfer function
  • scale_fac (float) Gain factor
  • t_samp (float) Sampling interval in seconds
  • nfft (int) Number of FFT points of signal which needs correction
Return type:

numpy.ndarray complex128
