摘要:
The subrange-type A/D converter includes A/D converters in multiple stages (204, 212), with their driving clock frequencies being in certain relationship so that they are used commonly for the A/D conversion of the high definition television signal and the A/D conversion of a test signal for detecting the transmission characteristics.
