Hide and Show Time Scope
Create a sine wave signal and view it in the scope.
Fs = 1000; % Sample rate signal = dsp.SineWave(Frequency=50,SampleRate=Fs,... SamplesPerFrame=100); scope = timescope(SampleRate=Fs,TimeSpanSource="property",... TimeSpan=0.25,YLimits=[-1 1]); for ii = 1:2 xsine = signal(); scope(xsine) end
Hide the scope window.
if(isVisible(scope)) hide(scope) end
Show the scope window.
if(~isVisible(scope)) show(scope) end
Clean up workspace variables.
clear scope Fs sine ii xsine
Input Arguments
scope
— Scope object
scope object
Scope object, specified as one of the following:
spectrumAnalyzer
objectdsp.ArrayPlot
objectdsp.LogicAnalyzer
System object™timescope
objectdsp.DynamicFilterVisualizer
object
Example: myScope = spectrumAnalyzer;
show(myScope)
Version History
Introduced in R2011aR2024a: dsp.SpectrumAnalyzer
object warns
The dsp.SpectrumAnalyzer
System object warns in R2024a. Use the spectrumAnalyzer
object instead.
Update Code
No updates to your code are required except replacing instances of
dsp.SpectrumAnalyzer
with
spectrumAnalyzer
.
This table shows how the show
function typically uses the
dsp.SpectrumAnalyzer
System object and explains how to update existing code to use the
spectrumAnalyzer
object.
Discouraged Usage | Recommended Replacement |
---|---|
scope = dsp.SpectrumAnalyzer; show(scope) |
scope = spectrumAnalyzer; show(scope) |
R2022a: Support for dsp.SpectrumAnalyzer
object will be removed
The show
function will stop supporting the
dsp.SpectrumAnalyzer
object in a future release. Use the
spectrumAnalyzer
object instead.
