- Abstract:
- Data processing of measurement data is a topic of paramount importance in every measurement system. Obviously sensors, signal conditioning and microprocessor specifications dictate important metrological characteristics of an embedded measurement system, namely: accuracy, resolution, repeatability and reliability. However, nowadays smart sensing systems and advanced signal processing techniques can improve measurement system’s performance and flexibility relaxing hardware specifications and associated cost. This paper pays particular attention to curve fitting based on Gaussian interpolation techniques. Experimental voltammetry data is used to evaluate heavy metals concentrations in water. Advantages of Gaussian interpolation techniques to detect heavy metals and associated concentrations will be highlighted using a comparative analysis with the results provided by classical interpolation methods.
