Counter type remote control receiver producing binary outputs correlated with numerical commands of a companion remote control transmitter

摘要

A remote control receiver for processing signals representative of a desired television channel number, each channel number being identified by a control signal lying in a respective band of frequencies. The channel number representative control signals are supplied to a multi- stage counter which is also supplied with regularly recurring timing or clock signals. The clock signals determine counting intervals during which the number of cycles of the received control signal are counted. The counter is arranged to provide frequency divided output signals having binary digits which correspond to a binary coded representation of the channel number.
