3 Working with Signals

Viewing Signals
The following blocks in the DSP Sinks library are the key blocks for displaying
signals:
•Matrix Viewer
•Spectrum Scope
•Time Scope (Simulink Scope)
•Vector Scope
The following sections provide an introduction to how these blocks are
commonly used:
•“Displaying Signals in the Time-Domain” on page 3-80
•“Displaying Signals in the Frequency-Domain” on page 3-82
•“Displaying Matrices” on page 3-83
Displaying Signals in the Time-Domain
The Vector Scope block can display both time-domain and frequency-domain
data. It differs from the Spectrum Scope in that it does not compute the FFT of
inputs.
Example: Displaying Time-Domain Data
In the model below, two frame-based signals are simultaneously displayed on
the scope.
To create the model, first load the
mtlb signal.
load mtlb % Contains variables 'mtlb' and 'Fs'
