Title: High voltage power supply circuit
Inventor: IMAMURA NOBUAKI
IPC: H04N3/185
Filed: 1993-07-29
Abstract: PURPOSE:To obtain the high voltage power supply circuit suitable for multi- scanning drive of a cathode ray tube. CONSTITUTION:A horizontal drive signal is integrated by an integration circuit comprising an externally mounted resistor 32 and an externally mounted capacitor 33 of an operational amplifier 31 to generate a triangular wave and a DC component of the triangular wave is cut off by a capacitor 38. A clamp circuit 36 clamps a lower peak level of the triangle wave to be a power supply voltage of a reference power supply 34 and the result is inverted by an inverting amplifier 37, which generates a reference triangle wave. A comparator 20 compares the reference triangle wave with a detected high output voltage and applies a drive signal whose pulse width gets wider as the high output voltage drop increases to a MOS FET 11. A flyback pulse is generated by the LC series resonance by a resonance capacitor 6 and a primary coil 2 when the MOS FET 11 is turned off. A peak level of the flyback pulse gets higher as the ON period of the MOS FET 11 is larger, that is, the high voltage drop is larger and the high voltage drop is compensated and the high output voltage is stabilized.

Abstract: PURPOSE:To obtain a regenerative QDPSK signal having a fixed spectral shape by recording and regenerating each signal as a test signal in advance, detecting the spectral shape of the regenerative QDPSK signal and controlling the recording equalization characteristic of the QDPSK signal to be suitable value. CONSTITUTION:Each signal of a video signal, an FM audio signal and a PCM audio signal is recorded in advance and regenerated as the test signal, and the propriety of the spectral shape of the QDPSK signal is decided by detecting the spectral shape of the regenerative QDPSK signal (4-phase phase-modulated PCM signal). Thus, a control means 71 is provided to control the recording equalization characteristic of the QDPSK signal to be a suitable value by this deciding result. By this method, the QDPSK signal having always a fixed spectral shape is obtained without being influenced by a different recording mode, the characteristic variation of a magnetic head 19 and the characteristics of a magnetic tape 5, etc.
