- SFDR
Spurious-free dynamic range (SFDR) is the usable dynamic range before spurious noise interferes with or distorts the fundamental signal.
- THD
- SINAD
- ENOB
Effective number of bits (ENOB) is another way of specifying signal-to-noise and distortion ratio (SINAD). ENOB is calculated using the following formula:
