Abstract
PURPOSE:To enable to change the direct channel selection system simply, by using the continuous pulse having higher frequency than the response of channel decoder for direct channel selection binary signal. CONSTITUTION:The remote control signal fed from the transmitter 1 is converted into binary signal 52 with the ring counter 205 and it is transferred to the down counter 105. The down counter 105 is preset with the load signal from the differentiation circuit 208 to count the binary signal 52. The down counter 105 counts the clock 56 from the clock pulse generation circuit 108 until the count value reaches the preset value with the load signal. Since the clock 56 is transferred to the channel decoder 3, the number of pulses corresponding to the preset value of the down counter 105 is inputted and the desired channel is selected.
