Abstract
The optimum filter for improving the signal-to-noise ratio in a commonly encountered signal recovery situation is the ideal averaging filter. Approximants to the averaging filter response, with averaging times between 1 ms and 100 s, are realised by RC active networks having some novel properties. The use of these filters in place of the first-order low-pass filter leads to an improvement in the measurement rate by a factor of two or greater.Keywords
