Question

apply fourier theorem to analyse a square wave into a simple harmonic component​

Answer 1

Explanation:

The Fourier series expansion of a square wave is indeed the sum of sines with odd-integer multiplies of the fundamental frequency. So, responding to your comment, a 1 kHz square wave doest not include a component at 999 Hz, but only odd harmonics of 1 kHz. ... The Fourier transform is ∞∑k=−∞2sin(kω0T)kδ(ω−kω0)
