Question

What is the fundamental angular frequency in rad/sec for the given waveform?

• A. 5
• B. \( 5\pi \)
• C. 10
• D. \( 10\pi \)

Hint:

The fundamental angular frequency is the reciprocal of the period multiplied by \( 2\pi \).

Answer 1

The Correct Option is D

The given signal is a periodic signal with a period of 0.1 seconds (as seen from the waveform). The fundamental angular frequency \( \omega_0 \) is related to the period \( T \) by the formula: \[ \omega_0 = \frac{2\pi}{T} \] Substituting \( T = 0.1 \): \[ \omega_0 = \frac{2\pi}{0.1} = 10\pi \] Therefore, the correct answer is option (4).
