The fast Fourier Transform (FFT), added to an oscilloscope or digitizer, permits measuring the frequency domain spectrum of the acquired signals. This provides a different and usually helpful ...
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 ...
