Rl Transfer Function. Consider an rlcircuit where v 0 and there is no current. Kirchoffs voltage law eq.
If at t 0 a constant voltage v 0is put across the circuit for t 0 v land. The transfer function is given by ratio of output to the supplied input. The impedance in the inductor and capacitor branch are lumped and represented as 1 rlre s z2rliitc sc l 10 rl re sc.

It describes the discharging of inductors or capacitors via a circuit of no dependent source. Rl circuit transfer function time constant rl circuit as filter types of rl circuit. For completeness the transfer function is by inspection. Solved problems of transfer functiontopics discussed1 solved problem based on the transfer function of an rl circuit acting as a high pass.
