A data processing apparatus executes data processing with respect to an output of A/D conversion of an input signal. The data processing apparatus includes a high-frequency noise recognition unit. The high-frequency noise recognition unit detects number of peaks of waveforms of the input signal on a basis of the output of the A/D conversion. The high-frequency noise recognition unit determines whether or not the number of the peaks, which has been detected within a predetermined time, is equal to or larger than a predetermined value.
