ABSTRACT:
A follower response control circuit for a reference level establishing system having positive and negative follower circuits, each having means for defining a pre-established time constant producing, respectively, a positive peak signal and a negative peak signal in response to an input signal, and means responsive to the peak signals for establishing a reference level, including means for defining a second time constant for one of the follower circuits; switching means for selectively switching the means for defining a second time constant in and out of that one of the follower circuits; a direction detector circuit for determining whether the input signal level is moving toward the polarity of the peaks followed by that one of the follower circuits; a level detector circuit for determining whether the input signal is of the same polarity of the peaks followed by that one of the follower circuits; and a switch control responsive to the detector circuit for operating the switching means to introduce the means for defining a second time constant into that one of the follower circuits to alter temporarily the pre-established time constant of that follower circuit during the period when the input signal level is moving toward, and is the same polarity relative to the reference level as, the polarity of the peaks followed by that one of the follower circuits.
