EDN Magazine — 08.03.95 Improved circuit-analysis techniques require minimum algebra (figure)

FIGURE 3

Fig 3—Fig 2 is the circuit in Fig 1 simplified by removal of the dependent source. In (a), removal of R_Bfrom the circuit in Fig 2 provides additional simplification, making it easy to determine the port B input resistance with the input port shorted (b) and open (c).
