- jax.numpy.sinc(x, /)#
Return the normalized sinc function.
LAX-backend implementation of
Original docstring below.
The sinc function is equal to \(\sin(\pi x)/(\pi x)\) for any argument \(x\ne 0\).
sinc(0)takes the limit value 1, making
sincnot only everywhere continuous but also infinitely differentiable.
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 calculate
sinc(x), which has the same shape as the input.
