Chapter 3. Advanced Technique<br />
: Sum of Noise (excluding fundamental frequency, Harmonics, DC and Nyquist bins)<br />
: Total Number of bins<br />
: Total Number of bins of Harmonic<br />
: Total Number of bins of Noise.<br />
• SNR(Signal to Noise Ratio) : The ratio of the amplitude of the fundamental frequency to the<br />
Noise.<br />
ENOB(Effective Number of Bits) : The number of bits in an ideal converter that would be required to<br />
give the same SNR performance.<br />
• SINAD(Signal to Noise and Distortion) : The ratio of the amplitude of fundamental frequency<br />
to the Noise, but Noise include Harmonics.<br />
• THD(Total Harmonic Distortion) : The ratio of the rms sum of the harmonics to the rms value<br />
of the fundamental.<br />
• SFDR(Spurious Free Dynamic Range) The ratio of the rms signal amplitude to the rms value of<br />
the peak spurious spectral component. The peak spurious component may or may not be a<br />
harmonic.<br />
: The rms value of the peak spurious spectral component.<br />
• Total Power : The rms value of the sum of all spectral components.<br />
: Sum of Noise excluding DC and Nyquist.<br />
