ABSTRACT:
A remote control receiver for a television receiver remote control system having a memory capacitor and a field-effect transistor readout to provide a direct control voltage is shown. Circuit means illustrated as a diode connected in series with the memory capacitor limits the magnitude of the charge stored by the memory capacitor to prevent the field-effect transistor from being driven beyond cut-off by an excessive amount.
