What is an artifact in signal processing?

In natural science and signal processing, an artifact or artefact is any error in the perception or representation of any information introduced by the involved equipment or technique(s).

What is overshoot artifacts?

Another artifact is overshoot (and undershoot), which manifests itself not as rings, but as an increased jump at the transition. It is related to ringing, and often occurs in combination with it.

What is 64 point FFT?

The 64-point FFT is realized by decomposing it into a two-dimensional structure of 8-point FFTs. This approach reduces the number of required complex multiplications compared to the conventional radix-2 64-point FFT algorithm. The complex multiplication operations are realized using shift-and-add operations.
