Abstract
An adaptive filter, which combines the advantages of both short (about 0.5 s) and long (about 2 min) integrating time constants, is described. The recording time constant will be long for a steady level of input signal, but will proportionally shorten when there is a change in the average level of the input signal. If steady conditions continue after a change, the time constant will gradually become long again.
