摘要:
For the wireless remote control of an RF receiver having a remote control signal processing portion, the RF receiver being capable of being switched between an off state, an on state and an enabled state in which a channel is not being received but the remote control signal processing portion is operative, the remote control processing portion includes a remote control signal receiver unit and a memory circuit connected to receive signals from the receiver unit and to convert them into voltages which operate the RF receiver, and there is provided a remote control signal transmitter having a button or key for each channel and arranged to transmit, upon actuation of a given button, a carrier signal which is pulse modulated with a number of pulses corresponding to the selected channel. The memory circuit has one location for each such channel and an additional location which can produce an output voltage to switch the receiver from its on state to its enabled state. Only one memory location can produce an output voltage at any given time.
