Frequency Domain Analysis
The
Frequency Domain
page in the GUI performs the fast fourier transform (FFT) of the captured data,
and displays the resulting frequency domain plots of the selected channel of ADS7841. This page also
calculates key ADC dynamic performance parameters, such as signal-to-noise ratio (SNR), total harmonic
distortion (THD), signal-to-noise and distortion ratio (SINAD), spurious-free dynamic range (SFDR), and
effective number of bits (ENOB).
