Abstract

The line analyser circuit for a television receiver using two different lines standards has a horizontal output transistor (1), a line search coil (2), a horizontal output transformer primary coil (3), a damping diode (4), a resonance capacitor (5) and a conformance capacitor (6). To form a tuning circuit, the primary winding (3) of the transformer is connected to a capacitor (7) and a diode (8), and also to a switch (S1) so as to connect a supply voltage (E625) to obtain different settings of the tuned circuit according to the line standard used. The secondary winding (9) of the transformer is used with a diode (10) and a capacitor (11) to obtain a low voltage supply. The circuit can be used instead of two separate voltage supplies for two different line standards.
