Title: Eliminating circuit of harmonic distortion of fm modulating wave
Inventor: MIKI YUUJI
IPC: H04B1/10
Filed: 1982-05-24
Abstract: PURPOSE:To eliminate video disturbance due to the 2nd harmonic, by connecting a diode in parallel to a resonance circuit constituting a load impedance of a high-frequency amplifier circuit. CONSTITUTION:An FM modulating wave passing through a video and audio signal filter 2 of a video disc player is inputted to a base of a transistor (TR)13 of a high-frequency distortion eliminating circuit 19. When this FM modulating wave includes a harmonic, its waveform is distorted, and when a peak value of a voltage is larger than that of a normal FM modulating wave, a potential difference across a peaking coil 16 exceeds a rising voltage of a diode 17 with respect to a input positive half cycle. The diode 17 is conductive during that time, the load impedance of the TR13 is decreased and the circuit gain is decreased, then the waveform of an output voltage having a phase opposite to the input voltage is rounded for the peak at the negative half cycle and the harmonic is eliminated. Thus, the harmonic component included in the FM modulating wave is eliminated remarkably and the result is inputted to a FM demodulating circuit 4.

Filed: 1984-05-02
Abstract: PURPOSE:To speed up photo response by a method wherein an n type layer is formed on an i-type layer via protection film having a window in the titled element of p-i-n structure.
