Abstract
A decoder device has a reference voltage generating section for outputting first and second threshold level signals, a first comparator for comparing a stair-stepped waveform input signal and the first threshold level signal to output a comparison result, a second comparator for comparing the input signal and the second threshold level signal to output a comparison result, and a logical operation section for performing a logical operation between output signals of the first and second comparators to output a signal decoded from the input signal. A threshold level represented by the first threshold level signal intersects a riser section of one stepped waveform out of two adjacent stepped waveforms in the input signal, and a threshold level represented by the second threshold level signal intersects a riser section of the other stepped waveform out of the two adjacent stepped waveforms of the stair-stepped waveform input signal.
