Complex to Magnitude-Angle

Compute magnitude and/or phase angle of complex signal

• 

Libraries:
Simulink / Math Operations

Description

The Complex to Magnitude-Angle block outputs the magnitude and/or phase angle of the input signal, depending on the setting of the Output parameter. The outputs are real values of the same data type as the block input. The input can be an array of complex signals, in which case the output signals are also arrays. The magnitude signal array contains the magnitudes of the corresponding complex input elements. The angle output similarly contains the angles of the input elements.

Ports

Input

Port_1 — Input signal

scalar | vector | matrix

Complex input signal that the block computes and outputs the magnitude and/or the phase angle.

Data Types: single | double

Output

Port_1 — Output signal

scalar | vector | matrix

Output signal that is the magnitude and/or phase angle of the input signal. To choose the output, set the Output parameter.

Data Types: single | double

Parameters

Output — Magnitude and/or phase angle output specification

Magnitude and angle (default) | Magnitude | Angle

Specify if the output is the magnitude and/or the phase angle in radians of the input signal.

Programmatic Use

Parameter: Output

Type: character vector

Values: 'Magnitude and angle' | 'Magnitude' | 'Angle'

Default: 'Magnitude and angle'

Sample time (-1 for inherited) — Interval between samples

-1 (default) | scalar | vector

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

Dependencies

This parameter is visible only if you set it to a value other than -1. To learn more, see Blocks for Which Sample Time Is Not Recommended.

Programmatic Use

Block Parameter: SampleTime

Type: string scalar or character vector

Default: "-1"
