So, here we have been given the flow block diagram like g1 of s, the input is r of s, its output is x2 of s, goes to the second gain block g2 of s, then the feedback x1 of x goes to the third gain box g3 of x and finally here is the output cx.
00:35
So, you have to find the transfer function for this flow block diagram.
00:41
So, first of all we know that this output c of x, this should be equals to the gain by the input, right? so what is the gain g3 of s? that times of the input x1 of s.
01:00
So, from here this input x1 s will be goes to output cx by the gain g3 of x because we know the formula of gain is equals to output upon input and by using that we have been written this first statement and then we have written this second one.
01:23
Now, if we see for the second one that is g2, the output will be x1 of s and input will be x2 of s.
01:32
So, this can be written as x2 of s would be equals to the gain.
01:37
So, okay g1 of s would be equals to the gain g2 of s times of the input gx2 of s.
01:48
So, from here this x2 of s would become equals to this put the value of x1 of s from the above as we have calculated in the form of c of s...
