In the context of DSP, what does "sampling jitter" refer to?

A) The variance in timing of sample acquisition

B) The loss of signal during transmission

C) The delay introduced by filters

D) The distortion of the output signal

Answer: A) The variance in timing of sample acquisition

Explanation: Sampling jitter refers to the variability in the timing of when samples are taken in the sampling process, which can lead to errors and distortion in the reconstructed signal.
