Digital signal recorder

摘要

A digital signal recorder affixes m bits as a prefix to an input information word of n bits to be encoded into a channel word of n+m bits in parallel, divides the encoded channel word by a bit corresponding to a common divisor of the period of the channel word of n+m bits and the period of spectral energy according to a track pattern to time-division-multiplex the channel word of n+m bits and generates a selection control signal for selecting the channel word having the frequency characteristic of a desired pattern by using the spectrum data prestored according to the time-division-multiplexed channel word and the track pattern so that the selected channel word can be processed in real time and be recorded. <IMAGE>
