Title: Tsuyoshi Itaya: Innovator in Television Technology
Introduction
Tsuyoshi Itaya is a notable inventor based in Osaka, Japan. He has made significant contributions to the field of television technology, holding a total of 3 patents. His work focuses on improving the functionality and quality of television broadcast receiving apparatuses.
Latest Patents
One of Itaya's latest patents is a television broadcast receiving apparatus. This invention features a demodulating unit that includes a PLL part, which synchronizes the phase of an IF signal with an internally generated carrier signal. It outputs an out-of-synchronization flag signal when the IF signal and the carrier signal are unsynchronized. Additionally, a muting part mutes a sound intermediate frequency signal and outputs a noise signal of a predetermined level when the out-of-synchronization flag signal is activated. This innovation prevents abnormal sounds from being outputted from the speaker of a decode and output unit, even when an IF amplifier amplifies noise at maximum gain.
Another significant patent is related to a front-end circuit, tuner, and television broadcasting receiver. This invention includes a VCO that oscillates a local signal and a mixer that converts an RF signal into a baseband signal. It also features a DC offset cancel circuit that detects and eliminates any DC offset in the baseband signal. The local frequency control circuit ensures that the frequency of the baseband signal differs from the frequency spectrum of the luminance signal, thus preventing video distortion.
