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 n^th 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.
