An RL circuit may be used as a differentiator if the output is taken across the inductor

Question:

An RL circuit may be used as a differentiator if the output is taken across the inductor and τ << T (say τ < 0.1T), where T is the width of the input pulse. If R is fixed at 200 k Ω determine the maximum value of L required to differentiate a pulse with T = 10 μ s.
