A given cable has characteristic impedance Z0 = 100 Ohms. At a given position on the line, the voltage amplitude is 1 V.
-Draw a sketch (a snapshot at a fixed time) of the forward-traveling voltage and current waves on the line, showing their amplitudes and phases.-Draw a sketch of the backward-traveling voltage and current waves on the line, showing their amplitudes and phases.
-If you wanted to measure V0+ for a given line, what exactly would you measure and where would you do it?-Does V0+ depend on the load impedance that's attached to the line? Explain why or why not.-To measure V0+, would you need to turn on the voltage generator? Why or why not?
This document is shown a paper on Orthogonal frequency-division multiplexing with advantages, disadvantages and uses.
The power dissipated in the resistor R0 is 89 W when connected to a 10V source. Find the total dissipated power if 3 resistors identical to R0 are connected in series to a 10V source.
Compute the amount of time required to deliver 10 frames to the receiver with stop-and-wait flow control. Assume that all frames and ACKs are received correctly.
find the MIN permissible SAG for a span of 225 m using a copper conductor with 1.2 cm diameter and allowing a MAX conductor tension of 2200 kg/cm^2 . The horizontal wind pressure is 6 g/cm^2 and specific gravity of copper is 8.9
A load consists of a resistance R in parallel with a capacitor of reactance X. The load is fed from a single phase supply through a line of impedance 8.4 + j11.2 ohms. The rms voltage at the load terminal is 1200 at 0 degress V rms,
The probability that a person will install a black telephone in a residence is estimated to be 0.3. Find the probability that the tenth phone installed in a new subdivision is the fifth black phone.
what is the common mode of starting the synchronous motor. Explain the function of the damper winding popularly called as the "amortisseur winding". Indicate all circuit diagrams to explain working of the synchronous motor.
A certain lossless transmission line is terminated in a normalized load impedance of ZL,n = 0.5 j2 ohms. Use a Smith Chart to determine the answers to the following questions. Mark the position of the load impedance on the chart and label it ZL.
Traffic lights are being converted from incandescent bulbs to LED arrays to save operating and maintenance costs. Typically each incandescent light uses three 100-W bulbs, one for each color R,Y,G,A competing LED array consists of 61 LEDs.
A sequence of 10 bits is transmitted over a binary symmetric channel with bit error probability Pe. Assume that bit errors occur independently. The sequence is considered to be received in error if more than two bit errors occur.
A particle travels along the x-axis with postion ( measured in meters ) as a function of time ( measured in seconds ): x(t) = 5t^2-7t+2. (a) At what time or times is the particle at rest
Assume that life on Mars requires cell potential to be +100mV, and the extracellular concentrations of the three major species are following (mmol/L): Na+ : 145; K+ : 4; Cl- : 120. Choose one species and assume that other two permeabilities are ze..
