Resumen:
Accurate models for PWM modulators composed by the parallel connections of p-order power followed by a linear filter have been recently presented in the literature. In this paper we derive closed-form expressions for the impulse responses and frequency responses of those filters. This allows to predict the amplitudes and frequencies of the spurious components appearing in the baseband when using sinusoidal inputs and also to obtain closed form expressions for the THD.
