TV receiver deflection circuit - includes multifrequency oscillator, ramp generator and tension regulator

摘要

A deflection signal generator is for a TV receiver and uses an oscillator generating a regulable frequency between high and low values. A ramp generator receives the oscillator output to create a saw tooth wave form. A tensions regulating circuit feeds the ramp generator in response to high or low frequencies from the oscillator. Voltage transistors are from a high to a low level simultaneously with the frequency change from high to low level and vice versa. The regulator of the potential level comprises two transistors (X1, X2). The first of the two transistors (X1) is influenced through two resistors (R1, R4) in series between the source terminal (4) and earth. The second transistor (X2) is influenced by two other resistors (R2, R3) in the base terminal circuit.
