- The dominant harmonic frequencies are sidebands of the PWM frequency and multiples thereof.
- A harmonic frequency is an integer multiple of the fundamental frequency.
- The harmonic frequencies are exact integer multiples of the fundamental frequency.
- Therefore, the DTFT diverges at the harmonic frequencies, but at different frequency-dependent rates.
