[A computer program for the power spectra analysis of biomedical signals].
This paper presents a useful program for the power spectra analysis of biomedical signals on a microcomputer. The frequency spectra to show the allocation of frequency were calculated from the acquired biomedical signal via a window algorithm and the real signal special handling. The frequency spectra became normalized power spectra through algorithm and could be displayed on a monitor or printer in the mode of histogram. We have got good results using this program to compute the power spectra of phrenic nerve discharges from the rabbit.
