Question

Two systems with impulse responses h1( t) and h2(t) are connected in cascade.Then the overall impulse response of the cascaded system is given by

Answer 1

Answer:

overall impulse response of the cascade system is the product of H1 (s) and H2(s).

Answer 2

• The impulse response of a  dynamic system is its output when presented with a elaborated  input signal called impulse.
• Generally it refers to reaction of any dynamic system in response to external change.
• The impulse response is found by feeding x[n] = δ[n] into the system.
• The response of a system equal to zero t=0 to the unit step input is called unit step response.
• The response time is the time between when the user initiates an action, and when the computer starts to display the result.
• The formula of response time is
• waiting time= turn around time -burst time.
• The overall impulse response of systems connected in cascade in the time domain is given by the convolution of the two impulse responses, i.e. convolution h1 (t) and h2 (t).
• In the frequency domain, the overall impulse response is the multiplication of the impulse responses in the frequency domain.
