What is interpolation of signal?

Interpolation is the process of increasing the sampling frequency of a signal to a higher sampling frequency that differs from the original frequency by an integer value. Interpolation also is known as up-sampling.

How does Lagrange interpolation work?

Lagrange Interpolation Formula finds a polynomial called Lagrange Polynomial that takes on certain values at an arbitrary point. It is an nth degree polynomial expression to the function f(x). The interpolation method is used to find the new data points within the range of a discrete set of known data points.

What do you mean by interpolating polynomial?

Polynomial interpolation is a method of estimating values between known data points. When graphical data contains a gap, but data is available on either side of the gap or at a few specific points within the gap, an estimate of values within the gap can be made by interpolation.
