Abstract

PURPOSE: To enable to know easily the reception channel on the Braun tube screen, by providing the means displaying the lines or dots changing the location according to the tuning voltage fed to electron tuner on the Braun tube screen.
CONSTITUTION: The tuning voltage a3 of DC fed to the base of the transistor Tr11 changes up and down when the preset volume 7 is turned, in Figure, and the operation region is changed by selecting the band switches 20 and 21, and it moves to either of the regions b1 to b3. Next, when the voltage a2 is changed with the saw tooth wave voltage a1 fed to the base of Tr6, the both voltages are compared at the differential amplifiers 6, 11, Tr11 is turned off with a1>a2, and the collector waveform is as shown in (b). This is differentiated 15, 16 to obtain the pulse (c), which saturates Tr17 to obtain the waveform (d). Further, when the signal (d) is fed to the Braun tube drive circuit, the line which continuously and uniformly moves for the location can be obtained on the screen (e) by changing the reception channel.
