Analysis of an Active Electrical Network Using Signal Flow Graphs and Mason?s Gain Formula

The transfer function of an electrical network can be determined using various techniques, such as nodal analysis, Kirchhoff's laws, and the time constant method. Another method for algebraically determining the transfer function is to use a Signal Flow Graph (SFG). An SFG is a directed, weighted graph consisting of nodes and branches. We will create a signal-flow graph of an active electrical network and analyze it using Mason's Gain Formula and the reduction rules of signal-flow graphs.
