INTERPOLATION 10.1 10.2 10.3 10.4 Introduction Polynomial Interpolation Model-Based Interpolation Summary ? ?…? I nterpolation is the estimation of the unknown, or the lost, samples of a signal using a weighted average of a number of known samples at the neighbourhood points. Interpolators are used in various forms in most signal processing and decision making systems. Applications of interpolators include conversion of a discrete-time signal to a continuoustime signal, sampling rate conversion in multirate communication systems, low-bit-rate speech coding, up-sampling of a signal for improved graphical representation, and restoration of a sequence of samples irrevocably distorted by transmission errors, impulsive noise, dropouts, etc. This...
