Question

Determine the fundamental period of the following signal:sin60t.

(a) 1/60 sec

(b) 1/30 sec

(c) 1/20 sec

(d) 1/10 sec

I got this question by my college professor while I was bunking the class.

The above asked question is from Signal Classification and Properties in division Signals and Systems Basics of Signals and Systems

Answer 1

Right choice is (b) 1/30 sec

For explanation I would say: Consider the equation: sinΩ0t. Comparing this equation with the one given in the question: sin60t

⇒ Ω0=60π
