I am having trouble figuring out this step in an example question I've been given. I'm supposed to be finding the 'transfer function in the forward path'.
This image shows the block diagram (top) and what I have been told is the correct forward path transfer function (circled with red).
But based off of my understanding of that a forward path transfer function is, I would have said Gfp = 5 * s+4/(s+5)(s+8)
Where am I going wrong?
