Title: Electronic radio or TV program selector - uses integrated circuit ring counter controlled by rocker switches
Inventor: SEEBECK JUERGEN DIPL ING
IPC: H03J5/02
Filed: 1975-01-30
Abstract: The selector comprises an integrated circuit ring counter having step switch positions for each raido or television program. The input to the integrated circuit is via a differentiating network and a rocker switch with an off-centre position. The operation of the switch causes the counter to step in a forward direction until the required program number is selected. The operation of the rocker switch in the other sence causes a pulse generator circuit to provide n-1 pulses, where n is the number of the required program. This enables the ring counter to operate in a reverse sense. By means of the double action switch forward or backward incremental mode of selection can be obtained.
