Title: The Innovations of Tadashi Terada
Introduction
Tadashi Terada is a notable inventor based in Fukaya, Japan. He has made significant contributions to the field of electronics, holding a total of 3 patents. His work primarily focuses on enhancing signal processing technologies.
Latest Patents
One of his latest patents is a contour accentuation circuit for a color signal. This invention comprises a variable gain amplifier, an output circuit, and a differential circuit. The output circuit is designed to output the signal according to the output from the variable gain amplifier while also providing a constant level signal for output signals that exceed a predetermined amplitude level. The differential circuit differentiates the output signal from the output circuit, allowing the amplifier to accentuate the contour of the input signal based on the output control signal from the differential circuit.
Another significant patent is an AFC circuit for producing a ripple-free oscillator control voltage. This AFC circuit utilizes counters, flip-flops, and logic gates to generate a first pulse signal when the phase of a VCO output signal lags behind a reference signal. Conversely, it produces a second pulse signal when the VCO output signal leads the reference signal. These pulse signals control a switch that connects either a first or second constant current source to charge or discharge a filter circuit, ultimately producing a control voltage for the VCO.
