A method and apparatus for reducing the effect of inter-wave interference on signals read from a storage medium and to precisely digitize the read signals are described. An apparatus for digitizing a signal read from a storage medium according to an embodiment of the invention, comprises: a peak detector, for detecting a peak value for an amplitude of a signal read from the storage medium; a threshold value determiner, for employing the peak value obtained by the peak detector to determine a compensation value that is used for compensating for the effect of inter-wave interference on the signal, and for employing the threshold value calculated by the conventional method and the compensation value to determine a compensated threshold value; and a digitization circuit, for digitizing the signal by using the threshold value determined by the threshold value determiner. Optionally an interpolator may be used to obtain more accurate peak values which occur between sample points.

A power supply circuit for a CRT display device includes a low-voltage power supply switching circuit for supplying power to a horizontal oscillation circuit of the CRT display device, and a high-voltage power supply switching circuit for supplying power to high-voltage circuits of the CRT display device. The low-voltage power supply switching circuit includes an oscillator and a switching transistor. The oscillator is triggered by an output of the horizontal oscillation circuit, and the conductive state of the switching transistor is controlled according to an output of the oscillator. The high-voltage power supply switching circuit includes a switching transistor. The conductive state of the switching transistor of the high-voltage power supply switching circuit is controlled according to an output of the low-voltage power supply switching circuit. As such, the switching operations of the low-voltage and high-voltage power supply switching circuits is carried out at a same frequency and in synchronism with the output of the horizontal oscillation circuit.

摘要:
A picture display apparatus for displaying a picture by using a composite signal including tri-state binary synchronizing signals. A first horizontal synchonizing signal comprising a positive-polarity bilevel (the two-state) signal is generated by detecting a negative-polarity peak portion of an input composite picture signal to accomplish the horizontal synchronization of a picture by use of the first horizontal synchronizing signal whereby when the horizontal synchronization is stabilized, an output pulse produced from the first horizontal synchronizing signal is utilized to extract the tri-state binary horizontal synchronizing signal from the composite picture signal during the time of the output pulse thereby accomplishing horizontal synchronization of the picture by the tri-state binary horizontal synchronizing signal in the stable condition.
