Signal Conditioning in the Analogue Domain
Precision analog signal conditioning – A practical design study with a focus on the analogue domain. (Nov 2021)
Sensing and acquiring sub-millivolt signals in the presence of broad band noise, sensor interference, and other environmental effects are challenging. In this class you will learn how to design signal conditioning systems, in both the analogue and digital domain, to overcome these challenges and gather quality data from the sensor. The class will follow a design flow taking the attendee from component selection to a practical design.
This course will cover the analogue section of the design concluding with a practical demonstration of the analogue front end.
Another course will cover the digital section of the design covering ADC principles and techniques to further process the analogue signal
