WAVEFORM A/D CONVERTER AND D/A CONVERTER. |
摘要 |
<p>In order to implement high resolution A/D (or D/A) conversion, the differentiated waveform of an analogue (or digital) waveform signal is generated by a differentiated waveform generating unit (10). The differentiated waveform is cyclically distributed at the timings of clock signals (CK0) to integrators (141 to 14N) (N is an integer of 2 or more). These integrated outputs are converted into digital (or analogue) signals by converters (151 to 15N). These converted outputs are added by an adder (16). The added result is output as a digital (or analogue) waveform signal. <IMAGE></p> |
