Timeencoded

Timeencoded refers to data or signals in which information is conveyed primarily through the timing of events, rather than their amplitude or spectral content. In timeencoded representations, the value of a symbol is encoded in the interval between successive events, the precise time a event occurs, or in the duration of a pulse. The concept is used across several technical domains.

In signal processing and communications, timeencoded approaches include event-driven sampling and spike-time coding, where timing of events carries information. In neuromorphic engineering and computational neuroscience, time encoding describes how neural spikes convey information. Temporal coding contrasts with rate coding, where information is carried by average activity level. Timeencoded methods can be robust to amplitude variations and bandwidth-limited channels.

Common techniques include pulse-interval encoding, where symbol value maps to time gaps; pulse-width encoding, where the duration of a pulse represents information; and time-of-arrival coding, where the exact moment of an event matters. Hardware or software decoders reconstruct the original data from the timing pattern using clock references or event-driven logic.

Applications range from low-power sensory systems and asynchronous analog-to-digital conversion to neural prosthetics and high-speed communications. Practical deployment requires precise time measurement and careful handling of timing jitter and noise. Timeencoded representations can offer data efficiency in bursty or sparse signal regimes but may incur decoding complexity.
