2. Press and hold down the Ctrl key (or click the right mouse button).Press the mouse button, then drag the pointer to the Integrator block's input port or over the Integrator block itself. JNTU WorldJNTU WorldDownloaded From JNTU World ()

Simulink draws a line between the starting point andthe Integrator block's input port.Finish making block connections. When you're done, your model should look something like this. Controlling Execution of a Simulation The Simulink graphical interface includes menu commands and toolbar buttons that enable you to start, stop, and pause a simulation. Starting a Simulation To start execution of a model, select Start from the model editor's Simulation menu or click the Start button on the model's toolbar.

DEPARTMENT OF ELECTRONICS AND COMMUNICATION ENGINEERING ANALOG COMMUNICATIONS LAB 35 You can also use the keyboard shortcut, Ctrl+T,to start the simulation. Note:A common mistake that new Simulink users make is to start a simulation while the Simulink block library is the active window. Make sure your model window is the active window before starting a simulation. Simulink starts executing the model at the start time specified on the Configuration Parameters dialog box. Execution continues until the simulation reaches the final time step specified on the Configuration Parameters dialog box, an error occurs, or you pause or terminate the simulation. While the simulation is running, a progress bar at the bottom of the model window shows how far the simulation has progressed. A Stopcommand replaces the Startcommand on the Simulation menu. A Pausecommand appears on the menu and replaces the Startbutton on the model toolbar. Your computer beeps to signal the completion of the simulation. Ending a Simulink SessionTerminate a Simulink session by closing all Simulink windows. Terminate a MATLAB session by choosing one the Filemenu and Exit MATLAB.

DEPARTMENT OF ELECTRONICS AND COMMUNICATION ENGINEERING ANALOG COMMUNICATIONS LAB 36 4. Amplitude Modulation & Demodulation Aim: To generate amplitude modulated wave using simulink and demodulate the modulated wave. Software Required: MATLAB 7.0.4 Simulink Theory:Amplitude Modulation is defined as a process in which the amplitude of the carrier wave c(t) is varied linearly with the instantaneous amplitude of the message signal m(t).The standard form of an amplitude modulated (AM) wave is defined by ( )( )()[]tftmKAtscacπ2cos1+=Where aKis a constant called the amplitude sensitivity of the modulator.
