pulseinterval

Pulseinterval is the time between consecutive pulses in a pulsed signal. It is the inverse of the pulse repetition frequency (PRF) and is typically measured in seconds or milliseconds. In practical terms, a shorter pulseinterval corresponds to a higher PRF and a denser train of pulses, while a longer interval reduces the PRF.

In electronics and photonics, pulseinterval describes the timing of pulsed laser sources, radar transmitters, and digital communication schemes that rely on trains of pulses. A constant pulseinterval yields a fixed PRF, while a varying interval can introduce timing jitter or deliberate modulation of the PRF for signaling or ranging purposes.

In measurement and instrumentation, precise determination of pulseinterval is essential for timing accuracy, synchronization, and duty-cycle calculations. It is affected by clock stability, triggering accuracy, and system jitter. Common tools for measuring pulseinterval include oscilloscopes, time-interval analyzers, frequency counters, and high-speed digitizers.

In biomedical contexts, the term pulseinterval may refer to the interval between successive arterial pulses or heartbeats. In cardiology this is more commonly called the inter-beat interval or RR interval, but some literature uses pulseinterval to describe the same concept, especially in photoplethysmography and pulse oximetry.

The concept links to related quantities such as pulse width, duty cycle, and modulation schemes, and it is fundamental to timing analysis, synchronization, and signal design across diverse disciplines.
