Research on Fourier Transform Infrared Spectroscopy Processing Method Based on Butterworth Filter

Aiming at the problem of the performance degradation of Fourier transform infrared spectrometer due to the large signal noise interference, a Fourier transform infrared spectroscopy processing method based on Butterworth bandpass filter is proposed. First, the transfer function of the band-pass filt...
