he LPC932 can be used to create a Pulse Width Modulated PWM signal. That s an analog signal, with only 2 discrete levels, for example 0V and 5V and a constant period. The current value of this signal at a certain poiTnt of time is proportional to its

The fourier transform is the method of changing time representation to frequency representation. The discrete Fourier transform (DFT) is a one of the Fourier transform, used in Fourier analysis. It transforms one function that is time into anot
