What is Jitter?
Small fluctuations in the timing of clock or signal edges from their ideal positions. When sampling high-frequency signals, even slight jitter causes large voltage errors.
Field: AD/DA conversion
Jitter in the explanations
Since a sine wave's slope is proportional to frequency, jitter limits SNR to −20 log₁₀(2πf·tj).
