# Is there a separate word for the time domain when working with digital signals?

Typically the phrase "time domain" implies an analog signal x(t), but I've also seen it referring to a digital signal x[n]. Is there any phrase that refers to x[n], but not x(t)?

• discrete-time domain signals, $x[n],X[k]$ etc., are referred to as sequences... Apr 24 at 15:16
• If you want to be accurate: "digital" refers to a signal whose amplitudes are restricted to a finite set. "Digital" is not related to the properties of the signal's time domain.

• You are correct, in this case I'm referring to discrete digital signals vs. continuous analog signals. Apr 24 at 17:29
