Inverse FFT PtByPt VI

Owning Palette: Transforms PtByPt VIs

Requires: Full Development System

Computes the inverse discrete Fourier transform (IDFT) of the set of input data points specified by sample length. This VI is similar to the Inverse FFT VI. Wire data to the x input to determine the polymorphic instance to use or manually select the instance.

Note  By default, reentrant execution is enabled in all Point By Point VIs.

Use the pull-down menu to select an instance of this VI.

Inverse Real FFT PtByPt

	initialize, when TRUE, initializes the internal state of the VI.
	x is a complex-valued data point.
	sample length is the length of each set of incoming data. The VI performs computation on each set of data. The default is 100. sample length must be greater than 0.
	Inverse FFT{X} is the inverse real FFT of the set of input data points specified by sample length.
	error returns any error or warning from the VI. You can wire error to the Error Cluster From Error Code VI to convert the error code or warning into an error cluster.

Inverse Complex FFT PtByPt

	initialize, when TRUE, initializes the internal state of the VI.
	x is a complex-valued data point.
	sample length is the length of each set of incoming data. The VI performs computation on each set of data. The default is 100. sample length must be greater than 0.
	Inverse Complex FFT{X} is the inverse complex FFT of the set of input data points specified by sample length.
	error returns any error or warning from the VI. You can wire error to the Error Cluster From Error Code VI to convert the error code or warning into an error cluster.
