Complex to Real-Imag - Output real and imaginary parts of complex input signal

Library

Math Operations

Description

The Complex to Real-Imag block accepts a complex-valued signal of any data type that Simulink supports, including fixed-point data types. It outputs the real and/or imaginary part of the input signal, depending on the setting of the Output parameter. The real outputs are of the same data type as the complex input. The input can be an array (vector or matrix) of complex signals, in which case the output signals are arrays of the same dimensions. The real array contains the real parts of the corresponding complex input elements. The imaginary output similarly contains the imaginary parts of the input elements.

Data Type Support

See the preceding description. For more information, see Data Types Supported by Simulink in the Simulink documentation.

Parameters and Dialog Box

Output

Determines the output of this block. Choose from the following values: Real and imag (outputs the input signal's real and imaginary parts), Real (outputs the input's real part), Imag (outputs the input's imaginary part).

Sample time (-1 for inherited)

Specify the time interval between samples. To inherit the sample time, set this parameter to -1. For more information, see How to Specify the Sample Time in the Simulink documentation.
