If the unit step response of a network is (1 – e – α t), then its unit impulse response will be
-
- α e – α t
- α e – t / α
-
1 αe – α t
- (1 - α ) e – α t
- α e – α t
Correct Option: A
Unit impulse response of a linear, time invariant network is the derivative of unit step function response of the network.
Unit step response is (1 – e – α t)
∴ Unit impulse response = – (– α) e– α t = α e – α t
