Question

Calculate the time period of the waveform x(t)=24sin(24πt+π÷4).

(a) .064 sec

(b) .047 sec

(c) .083 sec

(d) .015 sec

This question was addressed to me in class test.

I would like to ask this question from Dynamics topic in section Dynamics of Electrical Drives of Electric Drives

Answer 1

Correct option is (c) .083 sec

Best explanation: The fundamental time period of the sine wave is 2π. The time period of x(t) is 2π÷24π=.083 sec. The time period is independent of phase shifting and time shifting.
