Block diagram representation

Rule :- 1.

block connected in crash guard series can be replaced by a single blog with transfer function equal to product of transfer function of individual block.




Rule :- 2

parallel block can be replaced by a single block with transfer function equal to algebraic sum of transfer function of parallel blocks.






Rule :- 3

To shift the summing point to the left of the block divided the signal and trying the something block by G's.





Rule :- 4

to shift the summing point to the right of the block x the signal entering the summing block by G's.



Rule :- 5

to shift the take off after a block at a block in series with all signal which are taking off from at that point having transfer function as a reciprocal of transfer function of the block beyond which take off point is to be shifted.




Rule :- 6

to shift the take off point behind a block add a block having a transfer function same as that of block beyond which takeoff point is to be shifted in cash card with all block at that take off point.
