ABSTRACT:
A data processor that gives necessary and sufficient precision of analog-to-digital (A/D) conversion results according to the processing contents and the processing mode includes an A/D converter that digitizes an analog signal by repeatedly sampling and holding the signal at a frequency given by a clock signal, a coordinates processing part that obtains one piece of processing data by averaging n pieces of data output from the A/D converter, and a sampling-time/frequency control part that changes the number n and the sampling frequency to obtain a necessary precision of digital data.
