sincx

Sincx is a term encountered in mathematical and computational literature, but it does not correspond to a single, universally agreed definition. In many texts it appears as a variable name, a function designation, or a shorthand for a scaled version of the sinc function. Because usages vary by author and discipline, precise meaning should be inferred from context or explicit definitions.

In mathematics, sincx is sometimes described as a variant of the sinc function. The classical sinc function is defined as sinc(t) = sin(π t)/(π t) for t ≠ 0 and 1 at t = 0; some sources write sinc_x(t) or sincx(t) to indicate a version with a scale parameter x affecting the argument, such that sincx(t) may be sin(π x t)/(π x t). Definitions differ, and no single formula is universally accepted.

In signal processing and sampling theory, scaled sinc-like functions arise in interpolation, reconstruction, and filter design. When sincx appears, it is typically in contexts involving a frequency scaling or sampling rate parameter, where the function is used to model ideal or approximate interpolation kernels.

In software and documentation, sincx may be the name of a function, library, or module related to numeric computation, interpolation, or Fourier analysis. Because project authors choose their own naming, the term can refer to different implementations or variants, with varying inputs and outputs.
