A VIRTUAL PERIODMETER FOR SIGNALS BURIED IN NOISE
C. Fosalau, M. Cretu, O. Postolache
Abstract:
The paper presents an instrument designed to measure the period of signal buried in noise and having a high degree of distortions. It works as a virtual instrument implemented on a personal computer that receives the digitized signal from a digital acquisition card or from a digital oscilloscope through the GPIB interface. Its operation principle is based on a new algorithm developed for assessing the period of the input sampled signal by comparing a witness segment of samples with the rest of the samples that compose the signal, till they overlap the best. The method, as well as the instrument was tested in laboratory and the results were compared with those obtained by using other known methods.
