Abstract
In a circuit for processing a useful signal which varies in amplitude between positive and negative values about a zero value and contains information in the locations of its zero passages, which circuit includes: a zero passage detector having an input; a first capacitor connected in series between a source of the useful signal and the detector input; and components for coupling the useful signal with a first equalizing signal during the positive value intervals of the useful signal and with a second equalizing signal during the negative intervals of the useful signal, the coupling components include sources of the two equalizing signals, controllable switches connected to each source for selectively coupling the corresponding equalizing signal with the useful signal; and a control pulse generator means connected for applying to each said switch control pulses derived from the useful signal and having a timing such that each switch is closed for a predetermined period during its associated intervals of the useful signal.
