Abstract
PURPOSE: To secure a circulating channel selection for all other channels within a short time by supplying the clocks of the same number as the channel number to be selected to the channel selection device in sequence with the fixed time interval via the start signals.
CONSTITUTION: Sequential channel selection device 1 of the tuner contains the channel selection buttons to perform selection for 12 channels and capable of switching of the sequential channels via the forward signals sent from control circuit 2. When switch 5 is pressed to carry out the circulating channel selection, the clock signals are applied to circuit 2 from clock generator 4. Circuit 2 supplies these clock signals to duo-decimal counter 3 and device 1. As a result, device 1 selects the next channel in sequence. When counter 3 counts 12 units of the clock signal, circuit 2 stops the supply of the clocks to device 1 and also reset counter 3.
