Opto-couplers and isolation: Digital/Analog Isolation applications. Study-Unit Aims: This study-unit introduces Opamp Frequency response and the notion of compensation. This leads to basic analogue filter theory and design. Various techniques associated with data conversion between the analogue and digital domains are introduced, allowing the student to select the most appropriate architecture for the purpose. The subject also serves as a platform to consolidate the student's electronics. A number of signal conditioning subsystems are also introduced and explained in the context of precision electronic methods of measurement. Project Work:- Design of a small data acquisition system: sensing, interfacing, digitization and display. Learning Outcomes: 1. Knowledge & Understanding: By the end of the study-unit the student will be able to: - Specify and describe analogue active filter circuits; - Describe the principles of operation of the popular types of ADCs and DACs; - Discuss the technical and practical differences, merits and demerits of selecting b etween various ADC or DAC architectures; - Discuss and select realistic specifications of a subsystem with clients or peers w ithin or beyond their own organization; - Describe the principles of operation of Photodiodes, Photovoltaic cells/Panels and O ptoisolation for both analog and digital systems. 2. Skills: By the end of the study-unit the student will be able to: - Characterize the frequency response of opamps and design opamp circuits using de-compensated opamps; - Design and build basic analogue filter circuits in standard Bi-Quad configurations; - Design a simple electronic instrument to read information from any analogue sensor and interface to a appropriately ADC for further digital processing; - Select the most appropriate ADC or DAC in relation to given requirements; - Design circuitry fit for a purpose by balancing numerous, often conflicting constraints and requirements; - Design a subsystem that meets stringent criteria of size, cost and performance.
