Signal Flow Graph (SFG) is an Alternative method to block diagram representation. Like block diagrams it does not consist of blocks, summing points and take-off points. It only of a network in which nodes are connected by directed branches. Definition: A signal flow graph is graphical representation of the relationship between variables of set of …
Transfer Function is the ratio of Laplace transform of the output to the Laplace transform of the input, assuming all initial conditions zero. In general Where x is the input of the system and y is the output of the system. When order of the denominator polynomial is greater than the numerator polynomial the transfer …
