Consider a satellite communication link with a one way propagation delay of 300ms between the sender and receiver, operating at 10Mbps using packets of length 1500bytes. Length of the ACK packet is also 1500 bytes.
a) What is the minimum timeout period required for the Stop-and-Wait protocol? The timer is set when the last bit is transmitted.
b) What is the maximum effective data rate of the link for this protocol?
c) Find the minimum window size with which Go-Back-N would be able to achieve 100% efficiency in the absence of any errors.
d) Find the data rate that can be achieved with Stop & Wait and Go-Back-N, if the frame error rate is 10-2 ?
A transformer has a primary voltage of 115v and a secondary voltage of 24v. If the number of turns in the primary is 345, how many turns are in the secondary?
An LVDT with associated signal conditioning will be used to measure work-piece motion from -20 to +20 cm. The static transfer function is 2.5 mV/mm. The output will be interfaced to a computer via an ADC.
Finding appropriate source for the electrical load, Have four circuits. One takes 9Vdc, two 5Vdc, and last one takes 12Vdc. Have variable transformer for source. How do I calculate or choose the voltage needed to run all four circuits with out blo..
our senior design team is designing a force sensor to measure a force signal and analyze the signal with a microcomputer (binary system). The analog force signal is between 10 N and 70 N and has the frequency bandwidth of DC - 1000 Hz.
a plane wave is obliquely incident onto the planar interface between mismatched, lossless, nonmagnetic, uniform media, yet undergoes no reflection. If incidence is at 54 degrees to the normal, at what angle to the normal does the transmitted wave ..
Plot the signal x(n) 0
Transmitting data at higher speeds generally requires a wider bandwidth, which is not always possible within FCC guidelines. In addition to the wider bandwidth, higher speed transmission also requires a higher transmit power. Why
Magnitude bode plot for any given transfer function Can some one teach me an easy way to make a bode plot for any given transfer function magnitude only (not phase).
Capacity, Data and Transfer Rates, Access Time of Disk Drive, A hard disk drive has 10 disks and 18 surfaces available for recording. Each surface is composed of 200 concentric tracks and the disks rotate at 7200 r.p.m.
An electric pencil sharpener is rated 240 mW, 6 V is connected to a 9-V battery and a series-dropping resistor Rx needed to power the sharpener. Calculate the value of the series-dropping resistor Rx needed to power the sharpener.
Consider an LTI(linear,time-invariant) system with input x(t) and output y(t). Suppose you know(measure) the step response, tha is , for x(t) =u(t), you know that y(t) = 2e^(-0.5t)*u(t). Find the output for the following different inputs
draw out a schematic that implements a 3-bit XOR gate, but consisting of only 2-bit NAND gates. Your schematic should have from 8-10 NAND gates, but NO other logic function such as OR, AND, INV gates can be in your final design.
