Return the normalized sinc function.
LAX-backend implementation of
Original docstring below.
The sinc function is \(\sin(\pi x)/(\pi x)\).
Note the normalization factor of
piused in the definition. This is the most commonly used definition in signal processing. Use
sinc(x / np.pi)to obtain the unnormalized sinc function \(\sin(x)/(x)\) that is more common in mathematics.
x (ndarray) – Array (possibly multi-dimensional) of values for which to to calculate
sinc(x), which has the same shape as the input.
