INSTRUMENTATION
Objective :
Instrumentation is essential in monitoring and analysis of any Physical system and its control. This course
deals with different types of transducers, digital voltmeters, oscilloscopes and measurement of non
electrical quantities.
UNIT-I Characteristics of Signals
Measuring Systems, Performance Characteristics, – Static characteristics, Dynamic Characteristics; Errors
in Measurement – Gross Errors, Systematic Errors, Statistical Analysis of Random Errors.
UNIT-II Signals and their representation
Signal and their representation: Standard Test, periodic, aperiodic, modulated signal, sampled data, pulse
modulation and pulse code modulation
UNIT-III Oscilloscope
Cathode ray oscilloscope-Cathode ray tube-time base generator-horizantal and vertical amplifiers-CRO
probes-applications of CRO-Measurement of phase and frequency-lissajous patterns-Sampling
oscilloscope-analog and digital type
UNIT-IV Digital Voltmeters
Digital voltmeters- Successive approximation, ramp, dual-Slope integration continuos balance type-Micro
processor based ramp type DVM digital frequency meter-digital phase angle meter-
UNIT-V Signal Analyzers
