Figure 30.12 shows a router using FIFO queuing at the input port. The arrival and required service times for seven packets are shown below; ti means that the packet has arrived or departed i ms after a reference time. The values of required service times are also shown in ms. We assume the transmission time is negligible.
a. Using time lines, show the arrival time, the process duration, and the departure time for each packet. Also show the contents of the queue at the beginning of each millisecond.
b. For each packet, find the time spent in the router and the departure delay with respect to the previously departed packet.
c. If all packets belong to the same application program, determine whether the router creates jitter for the packets.
If the resistance of the headphones is 24 Ω, calculate the voltage and current required from the dependent voltage source (Av in our model) to deliver 0.1 W to the headphones. How much power is delivered from dependent source? How much power is lo..
The nominal output voltage of a certain regulator is 8 V. The output changes 2 mV when the input voltage goes from 12 V to 18 V. Determine the line regulation and express it as a percentage change.
Compare the power contained in the sidebands to the total power in the modulated signal. What is the power efficiency in this AM scheme and calculate the PEP supplied by the AM transmitter - Write an expression for the normalized modulating signal.
4H-SiC is doped with 2 x 1017 cm-3 nitrogen donor atoms (Ec - Ed = 90meV). Use Nc = 4 x 1020 cm-3. a. Calculate the electron density at 300 K. b. Calculate the hole density at 300K after adding 2 x 1018 cm-3 aluminum acceptor atoms

A point charge of 20 [nC] is located at (4,-1,3), and a uniform line charge of -25[nC/m] lies along the intersection of the planes x=-4 and z=6. (a) Calculate D at (3,-1,0). (b) How much electric flux leaves the surface of a sphere of radius 5, ce..
if a rod of brass 0.35 m long is heated from 150 to 850c while its ends are maintained rigid determine the type and
The purpose of this assignment is to become familiar with the world of refereed technical journals. This can be a somewhat intimidating world because your work is held up for detailed scrutiny by one or more experts in your field, the "refutes".
For a two-tone input, use (10.43) to find the amplitude of the third-order intermodulation product, then use (10.44) to relate OP1dB to OIP3.
Design a device that creates a voltage that is a damped oscillation with a frequency of 5 radians per second and a time constant of 3 seconds. In particular, explain how initial conditions are to be handled.
Each subconductor's radius is 10 cm. There are two configurations, the first one is setting subconductors A and B as a bundle, and C and D as another bundle; the second is setting subconductors A and C as a bundle, and B and D as another bundle.
b. Find the Fourier Transform of signal x(t) (use the Fourier Transform definition) c. Write down the double-sided amplitude and phase spectra x(t) d. Plot the double-sided amplitude and phase spectra of x(t)
