Question

What is a fundamental angular frequency?

(a) The inverse of the fundamental time period

(b) The inverse of fundamental frequency

(c) Fundamental frequency in radians

(d) Fundamental frequency in degree

The question was asked in my homework.

I'd like to ask this question from Periodic Signals in portion Fourier Series of Signals and Systems

Answer 1

The correct choice is (c) Fundamental frequency in radians

To explain I would say: The inverse of the fundamental time period is called fundamental frequency. If it is F, then 2πF is called the fundamental angular frequency ie it is a fundamental frequency in radians.
