a. Given the random binary data sequence 0110001011, provide waveform sketches for (i) NRZ change and (ii)split phase.
b.Demonstrate satisfactorily that the split phase waveform can be obtained from the NRZ waveform by multiplying the NRZ waveform by +- -valued clock signal of period T.
Calculating a DC Current through the telephone handset, A telephone handset has a resistance of 600 ohm. It is connected to the local telephone exchange at a distance of 5 km by a twisted pair that has a loop resistance of 200 ohm per km
A heat engine operating in outer space may be assumed equivalent to a Carnot engine operating between reservoirs at temperatures TH and Tc The only way heat can be discarded from the engine is by radiation
n the conduction band of a semiconductor, it has a lower valley at the center of the Bril- louin zone, and six upper valleys at the zone boundary along [100]. If the effective mass for the lower valley is 0.1m0 and that for the upper valleys
How many turns are required for a circular loop of 100-mm radius to develop a peak emf of 10mV if the loop rotates 30r/s in the earth's magnetic field Take B = 60E-6T.
Calculate the inductive reactance per meter of a single-phase, 50-Hz, two-wire transmission line. Assume each conductor's radius is 3cm and the distance between the two conductors is 2m .
1) For a forwarard converter, derive the minimum value of Vr - as a function of the input voltage Vg, the duty cycle D, and the turns ratio N1/N2 - that will cause the transformer magnetizing current to be reset to zero by the end of the switching..
Suppose that the sequence 110010011 is used as a synchronization sequence preamble to a data packet. Propose a method that can be used to allow the channel to distinguish the synchronization sequence from an identical data sequence within the pack..
Generate a sine wave signal with amplitude A=1, and frequency=0.1592Hz. Using a uniform PCM method, quantize it ot a) 8-level and b) 16-level. Plot the original signal and the quantized signals on the same axes
a) Draw the state diagram b) Draw the schematic for the logic to implement this circuit using Inverters, AND gates, OR gates and D flip flops. Use the reverse side and additional sheets if needed.
In a typical mobile communications base station (or cell site), a radio frequency (RF) signal is amplified in the base station and then sent (over cable) to the antennas at the top of the tower.
The design must show all stages used in its development and must be implemented and tested in PSpice and suitable timing waveforms produced.
