If the input x(t) and output y(t) of a system are related as y(t)=max(0,x(t)), then the system is

Consider a linear time-invariant system whose input r(t) and output y(t) are related by the following differential equation:d2y(t)/dt2+4y(t)=6r(t)The poles of t...

The transfer function of a real system, H(s), is given as: H(s) = (As+B)/(s2+Cs+D) where A, B, C and D are positive constants. This system cannot operate as
