A transmission line having a 50 ohm characteristic impedance is to drive a load of 200 ohms.1)What is the reflection coefficient if the line is connected directly to the load?
2) What is the standing wave ratio on the main line under the conditions of part (1) above?
3)In rectangular form what is the input impedance of a λ/8 section of 50 ohm line connected to a 200 ohm load? Include a figure showing the configuration having the input impedance to be calculated.
4)What is the input impedance of a λ/4 section of 50 ohm line connected to a 200 ohm load? Give answer in rectangular form.
three light bulbs (P1= 30W, P2=40W, P3=50W) are connected in series to a 120v source find the current i through the bulbs. Each bulb is rated 120 volts. how much power is each bulb absorbing do they generate much light
Suppose that independent missiles A, B, C have probabilities .4, .5, and .6 of hitting the enemy's headquarters, respectively. Assume that the enemy's headquarters will be destroyed with a probability .3,
At some instant, it goes into regenerative braking. Calculate the armature voltage va at that instant, if the current ia is not to exceed 10A in magnitude. Assume that the inertia is large and thus the speed changes very slowly.
If the speed of the crate at A is 15 ft/s which is increasing at a rate v=3 ft/s^2, determine the magnitude of the acceleration of the crate at this instant. [crate is on an incline sliding back toward the orgin at a distance of 10ft
Signal Definitions are A.H, B.L ,C.L, D.H and Z.L. It is recommended you apply DeMorgan's Theorem first to the above equation. Draw (on paper) a circuit diagram implementing Z, using the minimum number of gates.
Design a VDHL file controller to operate two separate sets of three traffic light signals, one for each direction. Use eight LEDs as shown in to represent the outputs. The Time in This State can be met in several ways.
1) Calculate the open circuit voltage VOC (ZL removed) (magnitude and phase angle) 2) Calculate the Thevenin Equivalent impedance ZTH for this circuit (magnitude and phase angle)
