DITDIT

Ditdit is a hypothetical data-encoding scheme described in theoretical discussions of minimalistic digital communication. The name derives from the "dit" unit, a short pulse. In ditdit, data is represented by the number of consecutive dits in a fixed time slot: a single dit encodes 0, a pair of dits encodes 1. A slot boundary is defined by a silent interval, and consecutive slots are separated by a standard gap.

Operationally, a message is a sequence of slots; each slot yields one bit. The scheme emphasizes simplicity and timing resilience: the encoding uses only one symbol type (dit) and relies on time-domain structure rather than complex modulation. Decoding is achieved by counting pulses within each slot and mapping to bit values. To improve error detection, simple framing and a parity bit may be added.

Applications and evaluation: Ditdit is discussed as an archetype for ultra-low-bandwidth links, where receiver complexity must be low and power consumption is critical. It is not intended for high data-rate networks and is sensitive to drift if slot timing is not maintained. Some analyses compare ditdit with other minimalist schemes to illustrate trade-offs between reliability, throughput, and hardware cost. Variants may extend the concept by allowing three-dit symbols for a two-bit symbol, at the cost of complexity.

Name and usage: The term is used in academic exercises and in fictional or hypothetical contexts to illustrate basics of digital encoding. It is not employed as a standard protocol in real-world systems.
