Credit points: 15

Subject outline

This unit concerns electronic instrumentation and sensors for biomedical, industrial and scientific applications: Sensors/transducers; signal conditioning; signal processing; data conversion and data presentation, single/multi-channel acquisition systems. Design of single, compound and hybrid-transistor amplifiers, current sources, active loads, power semiconductor thermal performance and safe operating area. Op amp circuit design and application, instrumentation amps, feedback amps and stability. Power supplies: transformers, rectifiers, filters, regulators, protection circuits. Measurement characteristics and errors, interfering/modifying inputs. Industrial/medical electrical safety, signal grounding, ground loops, electrical isolation, sources of internal and external noise, interference and shielding, signal-to-noise ratio, active filters for noise reduction. Sensors (eg flow, pressure, temperature, displacement, strain, motion, chemical/biomedical electrodes).
