Sinc function - Wikipedia
网页It is an interpolating function, i.e., sinc(0) = 1, and sinc(k) = 0 for nonzero integer k. The functions x k (t) = sinc(t − k) (k integer) form an orthonormal basis for bandlimited functions in the function space L 2 (R), with highest angular frequency ω H = π (that is, highest cycle frequency f H = 1 / 2 ). Other properties of the ...

The Sinc Function - Stanford University
网页The sinc function, or cardinal sine function, is the famous ``sine x over x'' curve, and is illustrated in Fig.D.2. For bandlimited interpolation of discrete-time signals, the ideal interpolation kernel is proportional to the sinc function
网页Note: Usually X(f ) is written as X(i2 f ) or X(i!). This corresponds to the Laplace transform notation which we encountered when discussing transfer functions H(s). We can interpret this as the result of expanding x(t) as a Fourier series in an interval [ …
