10.5 FEATURES OF RL CIRCUIT STEP RESPONSE
Step response in the electrical circuit analysis context implies the application of the unit step function, u(t), as the input with a set of zero-valued initial conditions specified for the circuit at t = 0– . The response to this unit step application can be described in terms of a chosen circuit variable, which may be a voltage variable, a current variable or a linear combination of voltage and current variables. We had chosen the current through an inductor as the response variable in the case of series RL circuit. The current waveform with zero initial condition (initially relaxed circuit) was shown to be
The primary objective of applying an input function to a circuit is to make a certain ...
