Chapter 6, Problem 18P

Prelab Information 1. Laboratory Preliminary Discussion First-order Low-pass RC Filter Analysis The first-order low-pass RC filter shown in figure 1 below represents all voltages and currents in the time domain. It is of course possible to solve for all circuit voltages using time domain differential equation techniques, but it is more efficient to convert the circuit to its s-domain equivalent as shown in figure 2 and apply Laplace transform techniques. vs(t) i₁(t) + R₁ ww V₁(t) 12(t) Lic(t) Vout(t) = V2(t) R₂ Vc(t) C Vc(t) VR2(t) = V2(t) + Vs(s) Figure 1: A first-order low-pass RC filter represented in the time domain.

I need help with this problem and an explanation of the solution for the image described below. (Introduction to Signals and Systems)

How do we know that D1 is forward bias and D2 is reverse biased?

Solve it in a different way than the previous solution that I searched for

A lossless uncharged transmission line of length L = 0.45 cm has a characteristic impedance of 60 ohms.  It is driven by an ideal voltage generator producing a pulse of amplitude 10V and width 2 nS.  If the transmission line is connected to a load of 200 ohms, sketch the voltage at the load as a function of time for the interval 0 < t < 20 nS.  You may assume that the propagation velocity of the transmission is c/2. Answered now answer number 2. Repeat Q.1 but now assume the width of the pulse produced by the generator is 4 nS. Sketch the voltage at the load as a function of time for 0 < t < 20 nS.

Solve this experiment with an accurate solution, please. Thank you.

A lossless uncharged transmission line of characteristic impedance Zo = 600 and length T = 1us is connected to a 180 load. If this transmission line is connected at t = 0 to a 90 V dc source with an internal resistance of 900, from a bounce diagram of this system sketch (a) the voltage at z=0, z=L, and z = L/2 for up to 7.25μs and (b) calculate the load voltage after an infinite amount of time.
