Abstract

A programming apparatus is provided for use with a signal receiver, such as a television or FM broadcast receiver, of the type whose tuning frequency is determined by a tuning control voltage or other tuning control signal, and whose power supply can be switched between an OFF and an ON condition in response to a power control signal. In the programming apparatus, a tuner control circuit generates a tuning control signal representing a predetermined channel or frequency when the power supply is switched to the ON condition; a timer generates a current time code representing the current time; a coincidence detector circuit compares the current time code with a program time code which is selectively entered and stored in a program time memory and provides a coincidence signal when these two codes are the same; a circuit applies the power control signal to the power supply to switch it to its ON condition upon occurrence of the coincidence signal; a program channel code corresponding to a desired channel or frequency is selectively entered and stored in a program channel memory; a discriminator provides a discriminating signal to indicate the stored presence of the program channel code in the program channel memory; and another circuit supplies the program channel code from the program channel memory to the tuner control circuit upon the occurrence of both the coincidence signal and the discriminating signal so that the tuner is tuned to the desired frequency at the desired program time.
