EMI 1 MID QUES..

1)determine the performance characteristics of instruments and explain them with respect to accuracy , resolution, precision, sensitivity, fidelity and lagging
2)describe how voltmeter and ammeter are constructed from basic galvanometer and explain with neat sketches
3) a) explain different types of signal sources .
b) explain working principle and functional view of function generator, random noise generators arbitrary waveforms
4)describe different types of wave analyzers with neat sketches
5)working principle of spectrum analyzers, distortion wave analyzers
6) describe features of CRT with neat block diagram
7) dual beam and dual trace CRO
8)short notes on delay line synchronous selector circuit, triggered sweep CRO, vertical amplifier
9)functional view of AF and RF function generators
10)how the range of voltmeter, ammeter, ohmmeter are extended and explain them in a clear way
