    摘要: A digital signal reproduction device including a data strobe circuit high in margin against noise and rapid in recovery from dropout of data and a digital signal reproduction method performed in such device. The digital signal reproduction device includes a pair of data strobe circuits (4, 5) and a switching circuit (3) for selecting one of the outputs of the pair of data strobe circuits, and a circuit (1, 2) for generating from the received signal a signal to control the switching circuit (3). The data strobe circuits (4, 5) ensure high reliability of the received signal against noise and a short time from dropout of the received signal to acquisition of a reproduction clock. The data strobe circuit (4 or 5) is selectable which is suitable for the reproduction state of the reproduced signal.
