Title: Amplitude modulation radio transmitter
Inventor: KOBAYASHI NAOKI
IPC: H03C1/00
Filed: 1990-10-31
Abstract: PURPOSE:To improve the overall efficiency of the transmitter by selecting plural taps of an impedance transformer with a switch means controlled by a modulation signal so as to control an output power of a high frequency amplifier. CONSTITUTION:When an input voice signal inputted to a terminal 6 is zero, an amplitude of an output signal is constant while a semiconductor switch S6 corresponding to nearly a center tap of an impedance transformer 10 is closed. When a voice signal is inputted to the terminal 6, a semiconductor switch 9 selects a tap of the transformer 10 in response to the amplitude of the voice signal. As a result, the amplitude of the high frequency signal is amplitude-modulated by the voice signal and the transmission of an amplitude- modulated wave is attained. Thus, through the constitution above, the amplitude amplifier consuming much power is not required and the overall efficiency of the transmitter is improved.

IPC: H04N9/04
Filed: 1990-11-02
Abstract: PURPOSE:To reduce production of a false color by applying color signal processing suitable for a picture pattern when the picture pattern from which a false color is easily generated is detected. CONSTITUTION:A matrix selection section 111 discriminates which RGB conversion section is to be used to minimize a false color in response to a pattern of an object and outputs the result to a switch 115.
