in matlab

A process adds signals A and B together to generate an output signal C. A=5sin(20000t)+sin(t)B=10cos(30000t)cos(t) Where is your candidate number, and t is time a) use MATLAB Simulink to model this process when 0t10 seconds, the model must be shown in the report b) display all the positive values of signal C on a scope c) all signals in the system must be displayed on scopes and shown in the report d) the Simulink model and the properties of blocks must be shown in the report
