What is Simulink Simulink is a software package for modeling, simulating and analyzing dynamical systems. It supports linear and nonlinear systems, modeled in continuous time, sampled time, or a hybrid of the two. Simulink offers a friendly, graphical environment, in which you can model systems in the form of block diagrams, by simply clicking and dragging blocks into a model window. Simulink has a comprehensive block library of sinks, sources, subsystems (linear, nonlinear, and time-varying

What is Simulink You can use all the facilities of MATLAB when running Simulink. Using Simulink, you can see data displayed in scopes as the simulation unfolds. Outside the simulation environment, Simulink serves as the primary link for targeting to chips, boards, and co-simulation platforms by means of automatic code generation.

Basic Operations Copy blocks (components) from library Dublicate blocks on Model Edit parameters Edit simulation parameters Simulate (run)

DSP Operations DSP blocks are different than general DSP uses frame base data double lines

Sample or Frame Base Data Most real-time DSP systems optimize throughput rates by processing data in “batch” or “frame-based” mode. A batch or frame is a collection of consecutive signal samples that have been buffered into a single unit. By propagating these multisample frames instead of the individual signal samples,
