Abstract : An automatic threshold circuit to establish a threshold that is a specified number of db above the input's rms frequency weighted noise value wherein the input is compared with the feedback threshold value, the result of which is coupled to a limiter for providing an output of +1, or -1 volt, depending on the input's relationship to the reference. The output of the limiter is combined with a preselected value and integrated. The integrated output is coupled through a clamping circuit that limits its output to positive values, which values are the feedback voltage coupled to the comparator. (Author)
