In this question, solution here is, as we know that the transfer function for a negative feedback system here is, for the first part, this is here x and here it is g of s, this is here h of s and here it is r of s plus, here it is negative.
00:41
So here, c of s divided by r of s is equals to g of s divided by 1 plus g of s multiplied by h of s.
00:57
Now second, for a cascaded system, here we have, this is g1 of s and this is g2 of s.
01:23
Here it is c of s and this is r of s.
01:28
Now this is here r of s and here it is g1 multiplied by g2, this is c of s.
01:39
Hence, the transfer function of the given system is c of s divided by r of s, this implies 1 divided by s multiplied by 1 divided by s plus 1 whole divided by 1 plus 1 divided by s multiplied by 1 divided by s plus 1 multiplied by 1 divided by s plus 2.
02:06
So this is equals to s plus 2 whole divided by s multiplied by s plus 1 multiplied by s plus 2 plus 1...
