<p>A digital signal receiver is structured to receive and demodulate a digital signal. Such digital signal may comprise, for example, a television signal of character multiplex transmission having the digital signal included in the vertical blanking period of the television signal and the digital signal receiver may be structured to reproduce the digital signal from the television signal. The digital signal includes a clock run-in signal (CRI), a framing code signal (FRC) and a bit serial data signal (DA) disposed in succession. An error of the framing code or the data signal cuased by a low frequency region group delay characteristic of a transmission path between the transmission and the demodulation is detected and, upon detection of the error, a waveform distortion of the framing code signal and the data signal is corrected by means of a correcting circuit such as an LC circuit, whereby an error of the data signal to be demodulated thereafter is prevented.</p> |
