### Re: Calculating Frequency

### Re: Calculating Frequency

you still seem rather confused about the correct tems and how this all works both in theory and in practice If we do a DTFT (a discrete time Fourier transform), what we get out of the DTFT algorithm is a set of 10K data points. no the dtft is continuous in frequency This is sufficient to reconstitut...
