Reactance, Impedance & Filter Circuits

Question 1

Steady State Response

Answer 1

An electronic circuit response to either DC signals or fixed sine, cosine or repetitive signals

Question 2

What need to happen for a circuit to reach steady states

Answer 2

Generally goes through a period of sudden changes, such as being switched from OFF to ON

Question 3

Transient Response

Answer 3

The response of the circuit to theses sudden change

Question 4

Step Response

Answer 4

The response of the stimulus to the electronic system is a step function (e.g. it goes from a low voltage level to a high voltage level)

Question 5

Why are RC and CR circuits are called first-order systems

Answer 5

Their behaviours are determined with a first-order differential equation

Question 6

First-order system transient responses

Answer 6

𝑣 = 𝑉 ! + ( 𝑉 “ − 𝑉 ! ) × 𝑒 # “! 𝑖 = 𝐼 ! + ( 𝐼 “ − 𝐼 ! ) × 𝑒 # “!
where 𝑉” and 𝐼” are the initial values of the voltage and current, and 𝑉! and 𝐼! are the final values of voltage and current
