Question

The most general form of complex exponential function is:

(a) e^σt

(b) e^Ωt

(c) e^st

(d) e^at

I have been asked this question during an online interview.

I would like to ask this question from The Complex Exponential topic in division Signals and Systems Basics of Signals and Systems

Answer 1

Correct choice is (c) e^st

Easiest explanation: The general form of complex exponential function is: x(t) = e^st     where s = σ + jΩ.
