# 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

## Properties

*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 may also be read like 'yes' and false like 'no'

**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.
