Applies a complex FFT on the input vector.

CFFT

Overview

This operator applies an FFT or an inverse FFT on a complex vector. The output of this equation will be a complex vector.

The output vector will be of equal length as the input vector, which has to be a complex vector. The length of the input vector has to be a power of two.

Operator ports

Input V_c: Specific sample type, see below.

Output V_c: Floating point value buffers

Inverse

type: True or False
The option to inverse the CFFT. False means a transformation from the complex time to the complex frequency domain.

Select one of those presets:
True or False
True may also be read like 'yes' and false like 'no'

Caption

type: Word or phrase
The name of the object in the project. This name must not contain '.', '$' nor '@' characters.

For more information about the rules and usage of the Caption property, please refer to "Caption property - background and usage".

Documentation

type: See description
Optional documentation of this object. If this object is an operator, the Documentation text is displayed below the operator symbol.

Details

If the inverse Fourier transform is required, then set the Inverse property to true.

The output spectrum will not be scaled. If the inverse property is set to true, the output signal will be divided by N.
