A data transmission system uses 16-ary(16 levels) base band signaling.
A.) determine the minimum BW of a noiseless channel to transmit at 12,000 bits/sec with zero ISI.
B.) Explain what pulse shaping(channel shaping) would be required above and why.
a) Design a minimum two-level NOR-gate network to realize the above function. b) Design a minimum three-level NOR-gate network to realize the above function.
A delta-connected source has a line-to-line voltage rating of 470 Vrms. Its wye-connected load has a power rating of 2125 W with a pf of .85 lagging. Find the rated phase currents.
assuming k>0 what is steady state the response of the above system due to an input of the form , x(t) = 2sigma(t)+u(t). where sigma(t) denotes unit impulse function and u(t) denotes unit step function
A three-phase overhead transmission line has a per-phase resistance of 0.15 ohm/km, and a per-phase inductance of 1.3263 mH/km.
If a silicon diffusion is doped with phosphorus (donors) at a concentration of 0.6 x 10^17/cm^3, what is the concentration of holes in this piece of silicon per cm^3 Assume ni = 1.45 x 10^10/cm^3, n = 1000 cm^2/V-s, p = 400 cm^2/V-s
A six pole, 400 V d.c. motor draws 110 A from the supply. The shunt field resistance is 200 Ohm and the armature resistance is 0.5 Ohm. The armature is wave wound with 600 conductors operates at a speed of 1200 rev/min when supplying full load.

Explain briefly from what you notice about the digital output values in (a) why a digital output value of an A/D converter is rarely the exact same digital value as the analogue input value.
What is correct symbol rate (pulse rate) for this link? What is the bit rate with BPSK modulation? What is the bit rate with QPSK modulation?
A positive charge of 625 nC is uniformly distributed around a circular ring of radius 3 m that is positioned in the x-y plane. The center of the circle is at the origin. The relative permittivity of the medium is Epsilon_r = 1.
