Title: | One AC comparator | Authors: | Avramov S. Zupunski I. |
Issue Date: | 1-Jun-1990 | Journal: | CPEM Digest (Conference on Precision Electromagnetic Measurements) | Abstract: | Detecting the difference between two periodic, arbitrary waveforms is described. The input signals have the same frequency (in the audio range) and are in phase. The inputs are combined into a composite signal carrying the information about the difference between the mean values of half-periods of inputs. The required sensitivity is achieved by integrating the composite signal. The instrument can detect an amplitude difference of a few ppm. The instrument is microprocessor controlled and can be used to maintain the stable ratio between amplitudes, mean values, or other characteristics of the two input signals. | URI: | https://open.uns.ac.rs/handle/123456789/13614 | ISSN: | 05891485 |
