Abstract
A signal path setting circuit for a digital recorder comprising: a digital-to-analog converter hereinafter referred to as a D/A converter to convert a digital signal into an analog signal, a first switch to supply to the D/A converter a selected signal from a plurality of digital signals including a first digital signal from recording and playing back means for making a digital recording and playback through a recording medium, a second switch to supply a selected signal from a plurality of analog signals including the analog signal from the D/A converter, and an analog-to-digital converter (hereinafter referred to as an A/D converter) to convert the analog signal from the second switch into a second digital signal which is adapted to be directly or selectively supplied to the recording and playing back means.
Claims6
A signal path setting circuit comprising:
- first switching means to select a signal from a plurality of digital signals including a first digital signal from recording and playing back means for making a digital recording and playback through a recording medium;
- D/A converter means to receive said selected signal from said first switching means and to convert this digital signal into a first analog signal;
- second switching means to supply a selected signal from a plurality of analog signals including said first analog signal from said D/A converter means;
- and A/D converter means to convert said analog signal from said second switching means into a second digital signal.
A signal path setting circuit comprising:
- A/D converter means to convert at least a first analog signal into a second digital signal;
- first switching means to select one of a first digital signal and said second digital signal from said A/D converter means and supply the selected one to recording and playing back means to digitally record and play it back through a recording medium;
- second switching means to select one of a third digital signal from said recording and playing back means and said first digital signal;
- and
- D/A converter means to convert said digital signal from said second switching means into a second analog signal, which is designed to have an output from an analog output terminal;
- and
- third switching means to select one of said first analog signal and said second analog signal from said D/A converter means and wherein said A/D converter means is so connected as to convert the selected one from said third switching means.
