<p>PROBLEM TO BE SOLVED: To obtain a microcomputer, capable of outputting an arithmetic result having high reliability by removing irregular signal waveforms. SOLUTION: This microcomputer is provided with an upper clip circuit for comparing a digital value outputted by an A/D-converting circuit 1 with a high level reference value A, thereby replacing the digital value which is larger than the reference value A with the reference value A, and a lower clip circuit for comparing the digital value outputted from the upper clip circuit with a low-level reference value B thereby replacing the digital value which is smaller than the reference value B with the reference value B. Thus, it is possible to remove irregular waveforms included in an analog input signal, by replacing the digital value with the reference values A and B.</p> |
