A Fast Fourier Transform (FFT) plot is generated by collecting a large number of conversion samples from the output of the A/D converter in a periodic fashion that is receiving an AC input signal.
Specifications for analog-to-digital converters (ADCs) often include a fast Fourier transform (FFT) plot, such as the one shown in the figure, for a 12-bit ADC with a single-frequency input signal. In ...
If we want to take samples of some analog waveform, as in doing analog to digital conversions at some particular conversion rate, there is an absolute lower limit to the rate of doing conversions ...
