1- Using MATLAB and SIMULINk make a project to do the following : There is an engineering system which accepts 3 inputs and return 2 outputs. the first input is a constant variable which accepts 1 and 0 . The second input is a sinusoidal waveform which is 10sin(2pi1t). the Third input is a sawtooth generator with the same amplitude and frequescy as sine waveform. If the first input is zero, all the outputs should be zero. Otherwise, the first output is the sum of the inputs and the second output is multiplication of the inputs. (Hint: using Simulink environment and matlab function block, you can easily implement this code)
