The amplifier generates amplified at its output. Igi .. nmsk; or the form of the signal applied to its noninvirtual input 20, which is about .4O; Un through the capacitor 17 to the deflection coils. While the capacitor 2 is charged, this signal is nullified by the vertical scan, and when the connector 2 is discharged, a vertical nosophagus occurs (1k. Flow through the deflection KaTyujKH, also through the resistor 10. The voltage removed from the resistor 10 is fed through the capacitor 12 the inverting input 21 of the amplifier and is directly proportional to the current flowing through the deflection coils.) This voltage represents a negative current gap, which greatly increases the quality of the amplifier. The tracejibiio, the circuit formed by the inductance of the deflection cushions and their parasitic capacitance, is, to a degree, damped by the large BiyipcHHUM resistance of the gfi in the reverse course of the open circuit. As a result, all the energy is used .uiH of generating a deflection signal, which, in the case of the Bcprsival return, passes through all I.1, g. OS 11M11 | ..; chzhenie.

By means of the jToro signal, the jagged signal is input to the compensation of the geometric displacement of the image in the television tube. The introduction of resistor 8 facilitates more complete utilization of the applied voltage. Since the amplifier in a state of rest due to its internal symmetry provides an output voltage equal to half the effective voltage, all the applied voltage cannot be used for the deflection. A resistor 8 connected between the positive terminal of the source I1a1sh and the inverting input 21 of the amplifier eliminates internal symmetry for more optimal use of the voltage at the output of the amplifier. The resistor 9 and the capacitor 16 provide the possibility of fully driving the transistors in the output stage (not shown) of the amplifier 5 and thereby further increasing the utilization of the supply voltage. The invention of the frame scan generator for a television receiver, comprising a sawtooth generator on a diode, an integrating capacitor, and a charging resistor, a differential amplifier covered by a negative feedback circuit, and a resistor connected in series with coil deflecting-sh, characterized in that , in order to increase the degree of utilization of the supply voltage, the inverting input of the differential amplifier is connected through a capacitor with a connection point of a resistor with deflection coils and through an additional resistor - with a power source.
