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. How does a MOSFET amplify electrical signals? While a minimum requirement for amplification of electrical signals is power gain, one finds that a device with both voltage an
what is serveces of operating system?
What are the modes used in keyboard modes? 1. Scanned Keyboard mode with 2 Key Lockout. 2. Scanned Keyboard particular Error Mode. 3. Scanned Keyboard with N-key Rollover
what are the electrical characteristics of TRIAC?
Plug and Socket Condition : In the same way that your knowledge of flexes and fuses is wasted if you don't care to ensure that flexes and cables are routed safely and sensibly, so
Explain the Limiting the Spectrum This low-pass filter is known an anti-aliasing filter. These filters are originated at the input to most applications. Since they are required
Q. Define amplification factor, drain resistance and transconductance and derive the relationship between drain resistance and trans conductance? Drain resistance It is the
Maximum power transfer theorem
The constants of an amplifier are given by A = 1, R i =10,000, and R o = 100. It is driven by a Thévenin source with v Th (t) = V O cos ωt and R Th = 20,000 . The amplifier o
Low-pass electronic filter: The capacitors and inductors are the reactive elements of the filter. The number of elements ascertains the order of the filter. In this situation,
