Frequency domain interpolation
Abstract
A formula is derived for interpolation between output samples of an FFT, i.e., in the frequency domain. Such a formula is useful for obtaining greater frequency resolution when two coarse FFT outputs are available. Consideration is also given to the effect of such interpolation on a weighted FFT.
