Viewing Data with Scopes
The DSP Sinks library provides six special-purpose scope blocks that you can use to view different kinds of signals. Use these to supplement Simulink's standard Scope block in your DSP models:
Buffered FFT Frame Scope.
The Buffered FFT Frame Scope block is similar to the FFT Frame Scope scope (below) but provides internal buffering of the input, which is assumed to be a sample-based signal. The Buffer size and Buffer overlap parameters that control the block's buffering operation are the same as those in the Buffer and Rebuffer blocks.
FFT Frame Scope.
The FFT Frame Scope block displays the magnitude of the FFT of the input, which is assumed to be a frame-based signal. Each channel of a multichannel (matrix) input is displayed independently.
Frequency Frame Scope.
The Frequency Frame Scope block displays a time-varying vector containing frequency-domain data. The block plots the elements of the input vector against frequency, using the input frame period and size, or a manually entered value, to determine the correct frequency placement.
Matrix Viewer.
The Matrix Viewer block displays an M-by-N matrix input by mapping the matrix element values to a specified range of colors. The number of input columns must be specified in the Number of columns parameter of the Image properties panel. The display is updated as each new input is received.
Time Frame Scope.
The Time Frame Scope block is the primary tool for displaying time-domain signals. It differs from the Simulink Scope block in that it displays one or more frames of data simultaneously
User-Defined Frame Scope.
The User-Defined Frame Scope block displays a sequence of vectors without making any assumption about the source of the data (time-domain or frequency-domain).
