摘要： A front-end circuit according to the present invention includes a VCO which oscillates a local signal, a mixer which converts an RF signal Frf into a baseband signal, a DC offset cancel circuit which detects a DC offset contained in the baseband signal and then eliminates the DC offset, and a local frequency control circuit which controls a frequency of the local signal. In a case where the RF signal is an analog television signal, the local frequency control circuit controls the frequency of the local signal so that a frequency of the baseband signal differs from each frequency spectrum of a luminance signal contained in a video signal which is generated by demodulating the baseband signal. This makes it possible to provide the front-end circuit which can prevent video distortion caused when a frequency spectrum is eliminated from the luminance signal.

摘要： Conventionally, it is difficult to design the logic of a Gray code counter that can be used in interlaced counting. Even though interlaced counting is possible with a Gray code counter, the number of simultaneously changing bits increases greatly depending on the number of counts skipped at a time. To overcome these problems, a Gray code counter according to the present invention has a consecutively counting Gray code counter that counts in increments or decrements of one, and an output value converter circuit that converts the Gray code data output from the consecutively counting Gray code counter into a Gray code corresponding to decimal counts as obtained by counting with (2 raised to a particular power minus 1) counts skipped at a time.
摘要翻译：通常，难以设计可用于隔行扫描计数的格雷码计数器的逻辑。即使使用格雷码计数器进行隔行计数也是可能的，同时更改位数可以根据每次跳过的计数数量大大增加。为了克服这些问题，根据本发明的格雷码计数器具有连续计数的格雷码计数器，以递增或递减1计数，并输出一个输出值转换器电路，其转换从连续计数格雷码计数器输出的格雷码数据成为与通过用（2升至特定功率减去1）计数获得的十进制计数相对应的格雷码，一次跳过计数。

摘要： A conventional up/down Gray code counter has both a logic circuit section for up counting and a logic circuit section for down counting, and thus has a large circuit scale. To overcome this inconvenience, an up/down Gray code counter of the invention has a one-way Gray code counter that can count only in one, up or down, direction and a highest bit selecting circuit that receives the highest bit of the data output from the one-way Gray code counter and that then outputs the bit selectively either intact or after inverting it.
