What is sine interpolation?
Sine interpolation is used in particular to improve digital waveforms measured by A/D converters. It consists of a convolution of the sampled data with the sine function. This results in a reconstructed analogue waveform, i.e. the insertion of intermediate points between sampled data.
What is interpolation in trigonometry?
Interpolation is the process of finding a function which goes through some given data points. For trigonometric interpolation, this function has to be a trigonometric polynomial, that is, a sum of sines and cosines of given periods. This form is especially suited for interpolation of periodic functions.
