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 delta-wye connected three-phase transformer is rated at 38 MVA with primary and secondary line voltage ratings of 345 and 125 kV, respectively. The transformer p.u. reactance is 10%, the p.u. no-load current is 0.1.
Design a parallel resonance circuit with resonance frequency of 30kHz and bandwidth of 20kHz and plot its frequency response.
The signal transmitted by a Base Station has a power of 1 mW at a distance of 1 m from the transmitter. Measurements have shown that the propagation exponent for the path loss is n=3 up to a distance of 1 km and n=4 beyond that.
Determine the Voltage across the electrical model of a cell membrane in a nerve cell
Assuming no feedback to the adversary until each attempt has been completed, what is the expected time to discover the correct password?
A terrestrial radio link transmits a CDMA signal from a base station using a spreading code with a chip rate of 1.0 Mchips per seconds. The message data rate of the signal is 10 kbps.
You are required to determine that this next generation transmission system will require a spectral efficiency of 5 bits/sec per Hertz.
Using the Nth order term only of the transfer polynomial, find the Nth order relationship for the Nth order products.
the worker's safety harness D-ring is attached to a 12-foot shock absorbing lanyard that is securely fastened to the structure at a point 40 feet above ground level. Does this arrangement violate OSHA standards for fall protection? Explain.
An underdamped sensor with a static sensitivity of K=1, undamped natural frequency of omega=1400 rad/s, and damping ratio of zeta=0.5 is used to measure a sinusoidal signal with a frequency of 6 kHz.
Laplace transforms enable interpretation and manipulation of different signals by viewing these signals as either time domain signals/pulse or else frequency domain representations
