For example, it is in application of the testing power supply of a low frequency immunity examination, or a class-D amplifier. In this paper, the authors show that the bandwidth of PWM power amplifier can be controller. This controller is implemented on a DSP (digital can be made wider with this controller. extended by using an approximate 2DOF (2-degree-of-freedom) digital signal processor).
