摘要： U.S. Pat. No. 3,684,920 issued on Aug. 15, 1972 and based on U.S. Patent Application Serial No. 37,668, filed May 15, 1970, describes a transistor deflection circuit employing an output stage of class B, push-pull complementary symmetry type and a Miller integrator approach for the sawtooth wave generation. This invention describes a modification to the discharge circuitry thereof to improve the vertical deflection stability in the presence of spurious pulses which tend to undesirably and randomly trigger and/or retrigger the discharge switch. An additional ''''blanker'''' transistor is employed to sense the voltage across the vertical yoke winding so as to bypass the spurious signals away from the discharge switch during the vertical retrace interval when the danger exists that the deflection circuits will be falsely triggered.

摘要： A sweep generator in which the forward conduction of an intermittently operated positive feedback path including a transistor and a pentode is maintained by the discharge of a grounded capacitor connected in the base circuit of the transistor. A biased diode is connected between this capacitor and the base terminal of the transistor to block current from flowing through the capacitor in response to an external synchronization signal applied to the base of the transistor.

摘要： Transistorized vertical deflection circuit employs output stage of class B, push-pull, complementary symmetry configuration with vertical yoke winding halves serially connected in output circuit. Miller integrator approach is used for sawtooth wave generation, with feedback waveform derived from yoke current sampling resistor. Discharge transistor is responsive to feedback of flyback pulses developed across serially connected yoke winding halves. Apparatus disposed between winding halves introduces modulated horizontal deflection frequency current components in winding halves for pincushion correcting purposes. One winding half of vertical deflection yoke is shunted by a capacitor of a value selected to introduce cancellation of horizontal deflection frequency components across yoke/pincushion circuitry, in order to minimize feedback of interlace-disturbing horizontal components in pincushion corrected vertical deflection circuit.

摘要： Wide angle (e.g., 110*), large screen (e.g., 25 inch diagonal) color television display system employs a narrow-neck (e.g., 29 centimeter diameter) color kinescope with a deflection yoke having toroidal horizontal and vertical deflection windings. While power requirements of toroidal horizontal windings are met by a thyristor horizontal deflection circuit, toroidal vertical windings are driven by a transistor vertical output amplifier in a quasi-complementary symmetry, Class B, push-pull configuration. Capacitor is provided in negative feedback path between amplifier output and driver input, establishing Miller integrator action for linear sawtooth wave generation. Diode in series with capacitor provides voltage rise aiding rapid turn-on of driver at end of retrace interval. Oppositely poled diode shunting first diode completes low impedance capacitor discharge path during retrace interval.

摘要： The current-feedback operational amplifier-based sinusoidal oscillator circuit includes a pair of CFOAs connected to each other using five resistors and two capacitors. The condition and the frequency of oscillation are fully coupled, and thus none of them can be controlled without disturbing the other. The oscillator circuit provides a high impedance output current and two low impedance output voltages.

摘要： A signal integrating capacitor receives signal current for an integration circuit. A current shunt is coupled to the capacitor. The integrated output is differentiated and degeneratively fed back to the shunting circuit to control the amount of signal current bypassed from the capacitor, thereby increasing the effective time constant associated with the capacitor.

摘要： A recurrent digital sweep signal starts an integrator fed by a constant current. The integrator includes push-pull Darlington stages, which act as alternately conducting controlled current sources for split deflection coils outside the integrator feedback loop. A phase shifter provides arcsine correction. A time-out circuit avoids excessive dissipation if the sweep signal should be lost.
