It is clear that both systems keep the general shape of signal similar. But do they have differences in saving same signal in both systems?
digital save it in binary mood so what is the effect of sampling rate and digital recording system on signal saving?
Analog record (old technology) means that the signal is printed on photographic support paper. You need to procedd as a photograph to extract your signal. While Digital means that your signal is recorded as numerical file.
Digital mode are stored in zero and one, and there are more easier to handle and manipulate , while analog data are continuous with great fidelity, but very difficult to handle. Because of this,most times analog data are digitized and converted into digital data.most state of the art equipment work with digital data.
