The conventional Goertzel Algorithm can be used to compute individual DFT coefficients. In case we need to compute some values of DTFT (that means, non-integer multiples of the fundamental frequency), slight modification must be done.
There are two files: the conventional and generalized Goertzel algorithm. No toolboxes needed.
The algorithm and its derivation is described in the article accesible at
Hi, Does it take of windowing the data to reduce spectral leakage?
Hi Pavel Rajmic,
Nice code. I want this for n-dimensions. Is there a way to extend this code to multiple, or general n-dimensions. I am extremely interested in this, and would be very helpful for my application, if it can be extended to n-dimensions.
very useful for detecting frequencies that are not integer multiples of 1/N
I updated the link to the PDF. Thanks!
