Latest Patents
One of Masuko's latest patents is a video signal scramble system. This invention features a transmitter encoder equipped with a gain selector that compresses the level of a horizontal sync signal component of a video intermediate frequency (IF) signal to scramble it. Additionally, it includes an AM modulation degree controller that superposes a control signal on an FM audio IF signal in the form of AM modulation. The transmitter encoder also has an oscillator circuit for generating sine waves and a mixer for combining these signals to provide the control signal. The receiver decoder is designed to detect the AM component of the FM audio IF signal, reproduce a composite signal, and expand the compressed level of the horizontal sync signal component.
Another significant patent is an automatic gain control circuit for video signals. This intermediate-frequency automatic gain control circuit generates an IFAGC voltage to control the gain of an IF amplifier based on the output signal level. It also provides an RFAGC voltage for controlling the gain of an RF amplifier in a tuner. The circuit includes a time-constant circuit and a time-constant control circuit that adjusts the time constant based on the output voltage level.
