Works2.1_RC circuit analysis

1) switch S1 on (1) for step response analysis - Run “Transient” simulation during 10 times of RC - Take from the response curve : • the time constant at U2(τ) = 0.632Ep and U2(5τ) = 0.993Ep • the rise time tr between 10% and 90% of the step response Ep - Compare : • the values of the time constant τ with RC ? • the value of tr with 2.2 τ ? - Run “Transient” simulation during 1/10 time of RC • Take the value of U2(0.1 τ) and compare it with the function f(0.1τ) = Ep*0.1τ • deduce the response performed by the RC circuit for t << τ . 2) switch S1 on (2) for frequency response analysis - Run “AC sweep” simulation, for frequency 1 Hz up 1 MHz - Take from the curve response : • the cut off frequency fc, the band width and deduce the function performed by the RC circuit • the difference in phase performed by the RC circuit
