Instead we use finite (but large) height, and finite (but small) width, and calculate the resulting area; if the area is less than one, the response will be proportionately smaller than the theoretical unit impulse response. The unit impulse response is, therefore, also a zero state response. We know that the unit impulse response is the transfer function, hence we can write: Y (z) X (z) = H (z) = z − 1 + 1 2 z − 2 1 − 3 5 z − 1 + 2 25 z − 2 where X (z) and Y (z) … Where _ (t – t0) is delayed unit impulse function.

The unit impulse signal is simply a signal that produces a signal of 1 at time = 0. Calculation of Impulse Response.3. Orthogonal impulse responses. This process of adding up a set of scaled and shifted copies of one vector (here the impulse response), using the values of another vector (here the input) as the scaling values, is convolution -- at least this is one way to define it. If the system is initially at rest, find the response of the system at time 3 to (a) a unit impulse at time 0 (b) an impulse of size 6 at time 0 (c) a unit impulse at time 2 4. response reaches more th99%an of the steady state value.
