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
