Time domain to frequency domain...and back again

[TsTan]

For inverse chirp z transform (not in base pkg), the input signal is chirp z of X. But my input signal is the signal in frequency domain (magnitude and phase). I think that VI is not gonna work for my input data.

Do a search on the site for inverse  transforms

Refer to the labview\examples\analysis\dspxmpl.llb for examples of using the Transforms VIs.

I have been searching this inverse transform since last week. There was some people had done this conversion using inverse chirp z transform in Mathcad for long time ago. I think some NI programming technician would know how to implement or have some idea about that.
