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.
Construction - UniJunction Transistor: Construction: The basic structure of uni junction transistor is shown in fig. (a). It essentially consists of a lightly doped N type s
(a) A universal shift register can shift in both the left-to-right and right-to-left directions, and it has parallel-load capability. Draw a circuit for such a shift register.
A three-phase, 220-V, 60-Hz, four-pole, wye connected induction motor has a per-phase stator resistance of 0.5 . The following no-load and blocked rotor test data on the motor are
1. An analog information signal, whose maximum frequency is 6000Hz, is to be transmitted using a PCM system. The quantization error must not exceed the 1 % of the peak-to- peak an
