BE 3600 - Biomedical Instrumentation3 lecture hours 3 lab hours 4 credits
This course focuses on the fundamental devices, circuitry and techniques needed to acquire and process biomedical quantities and signals. The application of displacement, force and pressure transducers in the conversion of physical quantities to electrical signals is discussed. Operational amplifiers are introduced and used in amplifier and filter circuits to process the signals. Non-ideal op amp properties, including finite gain, frequency response, stability, input and output resistances, bias currents and offset voltages, are treated in sufficient depth to permit design of high gain circuits capable of handling small DC and low frequency AC voltages. Transmission of physical variables through a medium to a sensor is treated in the case of an indwelling arterial catheter and pressure transducer. (prereq: BE 206 )
