In a Manchester encoded data decoder a clock component is extracted from input data inputted at a prescribed rate, the extracted clock component is taken as input and transition points are extracted from the signal waveform of the filter output, a clock signal of the same rate as the input data and which is in synchronism with the phase of the extracted transition points is generated, a data component is extracted from the input data, results of comparing the extracted data component and a prescribed value are outputted as a binary level signal; and the binary level signal, taken in using the clock signal, is outputted as NRZ encoded data corresponding to the input data.
