Abstract
An indication system for a television receiver displays a receiving channel number directly from a local oscillation signal of the turner and a signal showing the receiving band associated with the operation of the tuner. An initial value signal is generated from the signal showing the receiving band. The value of the initial value signal is subtracted from the result of counting the local oscillation signal for a predetermined length of time. The resulting difference is divided into six parts, thus producing a pulse signal coincident with the receiving channel number which is to be displayed on an indicator.
