摘要： A push-pull circuit formed of transistors drives a peaking capacitor of an amplifier circuit to enhance charge and discharge of the peaking capacitor. This reduces a bias current, resulting in reduction of a power consumption. A feedback impedance is connected to an emitter of a transistor to feed an output signal back to an input of the amplifier circuit as a current signal in a wide frequency range. Thus, a high-power, wideband amplifier is accomplished.

摘要： An image display apparatus capable of adjusting a display picture by an input unit through a computer body is disclosed. When the user inputs a control instruction for adjusting the display picture of the display unit by the input unit connected to the computer body, a control signal addition circuit prepares a control signal Sc corresponding to the control instruction and adds the control signal to a video signal R, G or B or a synchronizing signal Hs or Vs produced by a display control circuit during a vertical retrace period. A-control signal separation circuit separates the added control signal Sc from the video signal R, G or B or the synchronizing signal Hs or Vs produced by the control signal addition circuit. A display control circuit produces adjustment signals Sa and Sb on the basis of the control signal from the control signal separation circuit to adjust a video circuit and a deflection circuit. Thus, the user can adjust the display picture by the input unit near at hand without extending the hands to adjustment switches of the display unit.

摘要： A horizontal deflection circuit including a horizontal deflection output circuit and a horizontal sawtooth wave current generation circuit. The horizontal output deflection circuit has a horizontal deflection coil and an S-shape capacitor connected in series with the horizontal deflector coil for supplying a horizontal deflection current to the horizontal deflector coil and the S-shape capacitor in accordance with a horizontal drive pulse. The horizontal sawtooth wave current generation circuit supplies a horizontal sawtooth wave current to the S-shape capacitor in a direction opposite to the horizontal deflection current and has a power voltage thereof controlled so that a difference current between the horizontal deflection current and the horizontal sawtooth wave current flowing in the S-shape capacitor has an amplitude proportional to a horizontal deflection frequency raised to a power N, where N has a value greater than 1, thereby enabling continuous S-shape correction independent of changes in the horizontal deflection frequency. A display apparatus utilizing the horizontal deflection circuit provides for S-shape correction with a maximum linearity error at a constant value of less than 5%.
