摘要： A frequency discriminating circuit having a double tuned circuit with a transformer, which has a first and second resonant circuits. The first resonant circuit is composed of a capacitor, a primary winding of the transformer and a first variable inductance element and the second resonant circuit is composed of a capacitor, a secondary winding of the transformer and second and third variable inductance elements, wherein the quality factor Q of the second resonant circuit is much larger than that Q of the first resonant circuit. The center frequency of the frequency-response characteristic (so-called S characteristic) of the discriminating circuit can be adjusted by adjusting the second and third variable inductance elements and the linearity of the frequency response characteristic of the discriminating circuit can be adjusted by adjusting the first variable inductance element.

摘要： In a video signal reproducing apparatus having a cathode ray tube in which at least one electron beam is made to scan a screen in line-scanning and vertical directions while the intensity of the beam is modulated to establish the brightness of a video picture to be displayed on the screen, and in which bright picture portions are represented by respective high level portions of a video signal; a waveshaping circuit receives the video signal and acts thereon to provide a compensated video signal in which the width of each high level portion between the respective rising and falling edges is increased, the compensated video signal is employed to control the intensity of the electron beam, and the rising and falling edges of each high level portion of the compensated video signal are detected, as by a differentiating circuit or a delay line circuit, to provide respective output signals by which the scanning velocity of the beam in the line-scanning direction is modulated. The waveshaping circuit for providing the compensated video signal may be constituted by a delay line and an OR circuit having inputs to which the original video signal and the delayed video signal are applied, or by a differentiator receiving the original video signal and having its output applied to a polarity equalizer.
