Abstract
A linear display device provides a floating bar type of display for instantaneous peak values and instantaneous average values of an audio signal. Pairs of respective peak and average comparators are coupled to a source of fixed value bias voltages. The comparators produce outputs when the peak value and the average value of the audio signal exceeds the bias voltage. A logic circuit connected to outputs of each pair of comparators provides an output only when the bias voltage exceeds the instantaneous peak value.
