EDIT If this answer was not helpful enough, then you can break up into G=N/D (numerator zeros) andThe open loop transfer function of a unity gain negative feedback system is given as G ( s) = 1 s ( s 1) The Nyquist contour in the 𝑠plane encloses the entire right half plane and a smallThe summing node and the G(s) and H(s) blocks can all be combined into one block, which would have the following transfer function Y ( s ) X ( s ) = G ( s ) 1 G ( s ) H ( s ) {\displaystyle {\dfrac 4 1 Stability Of The Closed Loop System Engineering Libretexts Open loop and closed loop transfer function formula
