Abstract

PURPOSE: To make easy to see the both tuning state and frequency at a glance and to enable easily correct adjustment, by displaying the tuning state and the frequency on cathode ray tube with one display picture.
CONSTITUTION: The unit provides the tuner 1 in which the tuning frequency is controlled with the tuning voltage, frequency display pulse generator circuit 14 which detects the frequency of the IF output signal of the tuner and produces the tuning display pulses in horizontal or vertical period of which pulse width is changed according to the shift from the frequency in IF, and display pulse forming circuit 16 forming the display pulse through the production of substantial logical product output of the tuning display pulse and frequency display pulse. Further, this display pulse performs the display of picture in which the width and the length are both changed according to the tuning state and the frequency on the cathode ray tube 6. Thus, the tuning state and the frequency are easy to see at a glance to enable correct adjustment easily.
