Instrumentation And Data Acquisition

AY2014/2015 Semester 1

Signal Conditioning - Amplification:Operational amplifiers: ideal and practical operation. Typical applications and circuits - inverter, non-inverter, buffer, integrator, differentiator, summer, difference, comparator. Introduction to instrumentation and isolation amplifiers - CMRR. off-set currents and voltages. Filters:active and passive filters, simple filter design ,analogue filter design with common circuit. Basic Interference Problems. Data acquisition systems: sampling theorem, sample and hold, multiplexers, analogue to digital conversion, design of a data acquistion system. digital to analogue conversion. Transducers: properties of analogue sensors for temperature, force & pressure. Operation of an analogue actuator: the DC server motor.
