Abstract
A digital signal, such as obtained during playback from a DAT machine, includes a first component containing e.g. the audio content and a second component containing error recognition code. A signal processor derives in accordance with the second component an error signal representative of errors in the digital signal. A microcomputer then calculates an error rate signal. The error rate signal may be visually displayed or the error rate signal may be applied to the pre-amplifier circuits in the playback transducer stage to minimize the errors.
