Correct option is (d) 1250 Hz

Explanation: Periodic time = 4 ms = 4 × 10^-3

Fundamental frequency = \(\frac{10^3}{4}\) = 250 Hz

∴ Frequency of the fifth harmonic = 250 × 5 = 1250 Hz.

A periodic rectangular signal X (t) has the waveform as shown below. The frequency of the fifth harmonic of its spectrum is ______________
