Q. Explain Cathode-ray tube?
While the CRT display is one of the oldest, it still remains one of the most popular display technologies. The raster-scanned display devices work similarly to commercial television sets, whereas graphics display devices use different technologies to achieve extremely high resolution. A CRT video signal has only two levels, with a 0 level causing a dark spot and a 1 level causing a bright spot. The appropriate combination of 1s and 0s displays data on a CRT screen, with each character displayed by dot-matrix displays, typically in 5 × 7or7 × 9 display fonts.
Q. Explain the applications of emitter follower. Because of high input impedance and low output impedance an emitter follower is capable of transferring maximum power from the
Q. Explain the theory of thermal runaway? The maximum average power Pdmax which a transistor can dissipate depends upon the transistor construction and may lie in the

Determine the self inductance of the two coils: Two coils with a coefficient of coupling of 0.6 between them are connected in series so as to magnetize (i) in the same directi
Q. Biasing the BJT? A simple method of biasing the BJT is shown in Figure. While no general biasing procedure that will work in all cases can be outlined, a reasonable approach
Zero-Bias Equilibrium In a p-n junction, with no an external applied voltage, an equilibrium condition is arrived at in which a potential variation is formed across the juncti
A 3-phase transmission line is 200km long. The line has a per phase series impedance of 0.25+j0.45 Ω/km and shunt admittance of j7.2 μS/km. The line delivers 250MVA, at 0.6 lagging
First Generation (1946- 1654) In the first generation computer vacuum tubes and valves were used. These computer were very large in size ( thousands of square feet on the fl
With a maximum excess delay of and a chip duration of , the multipath components fall in delay bins. This means that we experience leakage of energy between chips and the channel i
