%% Display Complex-Valued Input Signal % At the MATLAB(R) command prompt, type <matlab:ex_timescope_complexinp % ex_timescope_complexinp> to open the example model. The following Simulink(R) % model appears. % % <<../timescope_example1_model_cx.png>> % %% % By default, when the input is a complex-valued signal, Time Scope plots % the real and imaginary portions on the same axes. These real and imaginary % portions appear as different-colored lines on the same axes within the % same active display. Run your model to see the time domain output, as % shown in the following figure. % % <<../scopes_cxrealimag.png>> % %% % The Configuration Properties dialog box controls the visual configuration % settings of the Scope displays. From the Scope menu, select *View* > *Configuration % Properties* to open this dialog box. Go to the Display tab. Selecting % the *Plot signal(s) as magnitude and phase* check box specifies the Scope % to plot the magnitude and phase of the input signal. The magnitude and % phase appear on two separate axes within the same active display. After % you select this check box, click *OK*. The active display shows the magnitude % of the input signal on the top axes. The signal phase, in degrees, appears % on the bottom axes. % % <<../scopes_cxmagphase.png>> %
