Unformatted text preview: ECE 2100 Homework assignment 3 Solution prelab Covered: Chapters 5-7: Inductors and capacitors, Natural and step responses of RC and RL circuits, natural and step responses of RLC circuits, under, over and critically damped responses. 1) Prelab: Consider the following RC circuit and RL circuits: a. For the RC circuit, what its time constant? τ =RC=560 Ω ·0.1 μ F= 56 μ s (alternate: accounting for 50 Ω in source and shunt, R=585 Ω b τ = 58.5 μ s ) b. What will the RC step response be? Hint: what are I( ∞ ) and Vout( ∞ ) if Vin(t)=1V·u(t)? Vout( ∞ )=1V, so Vout(t)= u(t)1V(1-exp(-t/56 μ s) c. For the LC circuit, what its time constant? τ =L/R=·1200 μ H /560 Ω = 2.14 μ s (alternate, R=585 Ω b τ = 2.05 μ s ) d. What will the LC step response be? Hint: what are I( ∞ ) and Vout( ∞ ) if Vin(t)=1V·u(t)? Vout( ∞ )=0V, I( ∞ )=1V/560 Ω , Vout(t)= u(t)1V(exp(-t/2.14 μ s) 2) Prelab: Consider the following RLC circuit which is driven by the function generator as...
