Signal recording-reproducing apparatus.

摘要

There is provided a digital signal recording and/or reproducing apparatus which converts an input analog signal into a digital signal and records the digital signal on a recording medium, or which reproduces a digital signal recorded on a recording medium and converts the digital signal into an analog signal. Since the apparatus has an analog signal level control means and a digital signal level control means disposed in front and at the rear of an A/D converter or a D/A converter and controlled in correlation with each other, the S/N ratio of a recording signal or a reproducing signal can be improved. <IMAGE>
