- > Is there a mathematical process resembling the terms "digital"/"discrete" and "analog"/"continuous"?
- Rounding (down, or up, or to the nearest integer) is he mathematical process which discretizes value.
- Multiplication by the [Ш-function (Dirac comb)](https://en.wikipedia.org/wiki/Dirac_comb) discretizes time.
> There is no such thing as digital signal. There is only digital information imposed on an analog signal. "Digital signal" is just a shorthand. [Prof. Donald Cox]

- Multiplication by the [Ш-function (Dirac comb)](https://en.wikipedia.org/wiki/Dirac_comb) discretizes time.
- > I always had trouble understanding the terms "digital" and "analog"...
- I'll can reply with a quote from a lecture by Prof. Donald Cox :
- > There is no such thing as digital signal. There is only digital information imposed on an analog signal. "Digital signal" is just a shorthand.
