Suppose you connect a circuit containing passive elements like resistors,inductors and capacitors to a voltage source.Now you provide and impulse to the circuit.Now my question is Whether the response by the circuit is impulse response, or a transient response or is it the sum of two I. E transient response and steady state response.Do we call this sum as impulse response or what?

Can someone please help me with this? I know how to calculate impulse response, have idea about convolution. I am expecting a more intuitive answer than a mathematical one. I want to understand what exactly is going in the circuit?

• 2An impulse response is caused by an impulse. A transient response is not defined; it could be due to an impulse, or a step, or a ramp (for instance). – Andy aka 33 mins ago
• (1) Ah, let me see. Let us first agree on what exactly is an transient response. Ref: Transient response: en.wikipedia.org/wiki/Transient_response. – tlfong01 17 mins ago
• No. You’re mistaking the impulse response for solutions to the partial differential equation. – DKNguyen 13 mins ago
• (2) Then Wiki follows this: In electrical engineering specifically, the transient response is the circuit’s temporary response that will die out with time. (3) It is followed by the steady state response, which is the behavior of the circuit a long time after an external excitation is applied. – tlfong01 12 mins ago
• (4) I think (1), (2), and (3) are enough to answer the OP’s question.. We don’t need PDE, convolution, or even mathematics. What we need is general intuition, applicable to electrical or mechanical. – tlfong01 3 mins ago  Edit  Delete
