Which one of the following is the impulse response of the system whose step response is given as c(t) = 0.5(1 - e-2t) u(t)?
The unit impulse response of a linear time invariant system is the unit step function u(t) for t > 0, the response of the system to an excitation e-at u(t), a > 0 will be
A system with an input x(t) and output y(t) is described by the relation: y(t) = tx(t). This system is
If a function f(t) u(t) is shifted to the right side by t0, then the function can be expressed as
The impulse response of a causal, linear, time- invariant, continuous time system is h(t). The output y(t) of the same system to an input x(t). Where x(t) = 0 for t < -2 is
