2.4 THE RESPONSE OF A HIGH-PASS RL CIRCUIT TO STEP INPUT

A high-pass RL circuit is represented in Fig. 2.2(b). If a step of magnitude V is applied, let us find the response. Writing the KVL equation:

Therefore, from Eq. (2.80)

As v_i = V, Eq. (2.79) can also be written as:

Applying Laplace transforms:

Taking Laplace inverse:

Similarly, ...
