Abstract: A remote control transmission circuit for generating a multicarrier under control of a single microcomputer. This transmission circuit is arranged so as to allow reduction of the number of the program commands and making it easy to perform a different process during the output of the multicarrier. The number of the shift circuits of the shift circuits 2a to 2f which are connected is set by a switching circuit 4. A change-over switch 6 performs the change-over operation as to whether a new shift circuit 5 is coupled. The change-over switch 6 is controlled by an overflow signal of a counter 7 whose count source is an inversion signal of the carrier (multicarrier) output 1. The control of the change-over switch 6 automatically controls the period for the correction of the carrier output 1 without the control due to the microcomputer.
