1. How to convert common block diagrams to signal flow graphs? 2. How to reduce block diagrams using signal-flow graphs? Essential Questions
Mason’s Gain Rule General Input-Output formula Introduced by American Electronics Engineer S.J. Mason. Use to calculate the overall transfer function of a system. This can also be applied directly to block diagrams, but the signal flow graph representation is easier to read.
Mason’s Gain Rule General formula for any signal flow graph ୀଵ Where: = number of forward paths = forward path gain of kth forward path = associated path factor (cofactor) = determinant of signal flow graph
