Consider four cosine-s square-, ramp-, and step-signals. The square- and cosine-signals have amplitude and frequency of one. Create a Simulink - based model to do the following tasks: 1) creates the signals and displays then graphically; 2) finds the new signal defined by: x(t)=sq(t)c(t)21r(t)2s(t) where s,c,r and s are square-, cosine-, ramp-, and step-signals, respectively. 3) displays graphically the four sigmals as well as x(i) on the same Scope; 4) finds the first derivative of the four signals and displays graphically each signal and its derivative on the Scope; 5) finds the integral of the signal x(t) and displays it graphically along with its integral on the same Scope
