Block diagram reduction feedback loop
WebFeb 3, 2011 · The diagram doesn't have a loop and even if it had a block, you couldn't use the feedback formula. When there's a simple line, you can always make one with H=1. Notice that in this example, you don't have feedback, the signal keeps going forward and never returns. Thus you have two systems in parallel. One that is H1=2/(s+1) and one … WebProblem 5.2.- Find the closed-loop Transfer Function T (s) = C (s) / R (s) for the system below, using block diagram reduction.
