topeltkanalilist

Topeltkanalilist is a term used in Estonian technical writing to describe a double-channel list—a data structure that represents two synchronized data streams as parallel channels. The word combines topelt (double), kanal (channel), and list (list). In practice, a topeltkanalilist models paired data points where each position i corresponds to a value on both channels.

The typical form of a topeltkanalilist consists of two sequences of equal length. Implementations may store the data as two separate arrays or as a single list of pairs. This structure helps keep operations on the channels aligned in time or order, meaning the streams must be kept in lockstep for correct interpretation.

Common operations include reading or writing a pair at a given index, appending new paired data, and slicing both channels simultaneously. Functional-style processing, such as applying map or zip-like operations, can be performed on the paired data. Validation routines often ensure that both channels maintain equal length after updates and that indices are within bounds.

Applications of topeltkanalilist appear in fields dealing with dual or synchronized data streams. Examples include stereo or multi-channel audio processing, sensor arrays that produce two correlated measurements, and communication or signal-processing contexts where two parallel streams must be processed in tandem.

Notes on usage: the term is primarily found in Estonian-language texts and may be used informally to describe any data structure that holds two synchronized channels. It is not a widely standardized formal data type; related concepts include paired lists, zipped lists, or two parallel arrays.
