Abstract
Apparatus for receiving remote control signals which comprise an alternat sequence of two chronologically successive pulses, the first pulse having a first predetermined frequency and the second pulse having a second frequency manually selected from a predetermined number of frequencies, each of the predetermined number of frequencies representing a command to be carried out. The receiver comprises a signal detector, a signal amplifier and a circuit for decoding the remote control signal into a group signal dependent on the first frequency and a command signal dependent on the second frequency. A controllable gate is provided for gating the command signal from the decoding circuit to a command signal register having a command signal input for each of the commands, and an input for blocking each command signal output. Means coupled to the command signal outputs implement the commands. A circuit responsive to the group signal controls the gate, while a circuit responsive to receipt of a command signal in the register causes the remaining command signal inputs to be locked.
