Abstract

1487784 Ultrasonic remote control MULLARD Ltd 16 Dec 1974 54183/74 Heading G4F In an ultrasonic system for remote control (e.g. of a television receiver) the signal transmitted consists of a sequence of four binary coded words, the first word SW is common to all the remote control functions, the second word MWX is an n-bit word particular to the selected remote control function, and the third CSW and fourth CMWX words are the complements of the first and second words respectively. The digital circuits for the transmitter and the remote receiver are described in details, Figs. 3-7 (none shown).
