Glossary - alphabet order - "J"
This refers to fluctuation among clock cycles, which can cause jittery images or bit errors during data transfers. Epson uses statistical techniques to regulate the following five types of jitter.
- Period jitter (peak to peak)
This indicates the range of fluctuation in multiple one-cycle periods (differential between maximum and minimum values)
- RMS jitter (δ)
This indicates the dispersion of fluctuation in multiple one-cycle periods (standard deviation)
Period jitter and RMS Jitter
- Random jitter
This is unpredictable jitter that occurs randomly.
- Deterministic Jitter
This is jitter caused by circuits, electromagnetic induction, external environmental factors, etc.
Random jitter and deterministic jitter Example of random jitter
- Accumulated Jitter (long-term jitter)
This indicates the dispersion of consecutive clock period fluctuation (standard deviation).
