1. The problem statement, all variables and given/known data I have this parallel system and i have found its transfer function.Now i have to find what is the differential equation that links the input and the output 2. Relevant equations u(t)=input, w(t)=output H(s)=w(s)/u(s)=s+1/s(s+1)+1 -->transfer function 3. The attempt at a solution I think i have to go backwards starting from H(s) but i dont know how to do it Any help???
