How does sinc interpolation work?
The well known and commonly used digital signal processing method for discrete sinc-interpolation is 'zero padding'. It is implemented by padding the signal discrete Fourier transform (DFT) spectrum with an appropriate number of zeros and performing the inverse transformation of the padded spectrum.
How do you write sinc in Matlab?
y = sinc( x ) returns an array, y , whose elements are the sinc of the elements of the input, x . The output y is the same size as x .
What is sinc in math?
The sinc function , also called the "sampling function," is a function that arises frequently in signal processing and the theory of Fourier transforms. The full name of the function is "sine cardinal," but it is commonly referred to by its abbreviation, "sinc." There are two definitions in common use.
