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.
What do you mean by interpolation?
Interpolation Meaning
In short, interpolation is a process of determining the unknown values that lie in between the known data points. It is mostly used to predict the unknown values for any geographical related data points such as noise level, rainfall, elevation, and so on.
What is interpolation in sampling?
In the domain of digital signal processing, the term interpolation refers to the process of converting a sampled digital signal (such as a sampled audio signal) to that of a higher sampling rate (Upsampling) using various digital filtering techniques (for example, convolution with a frequency-limited impulse signal).
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.
