Question

The general form of real exponential signal is________

(a) X (t) = be^at

(b) X (t) = (b+1)e^at

(c) X (t) = b (at)

(d) X (t) = be ^(a+1)t

This question was addressed to me in an online interview.

Asked question is from Elementary Signals in portion Signals and Systems Basics of Signals and Systems

Answer 1

The correct choice is (a) X (t) = be^at

To elaborate: X (t) = be^at is the most general way of representing the exponential signals where both b and a are real parameters.
