A COMPUTER PROGRAM FOR SIMULATING SOME SIGNAL-TO-NOISE ENHANCEMENT METHODS USED IN HIGH PERFORMANCE INSTRUMENTS

Abstract

A computer program for a personal computer was written to test seven noise filtering methods with simulated signals buried in noise for education. The methods tested were as follows: filtering by an RC network, accumulation, sampling with integration, smoothing by Savitzky-Golay filter, combination of accumulation and Savitzky-Golay smoothing, combination of integral sampling and Savitzky-Golay smoothing and filtering by Fourier transformation. The two combined methods have yielded the best results.
