Abstract [en]

The corrosion of pipelines in the oil and gas industry is a major concern

from an economic standpoint, as well as it is a major safety and environ-

mental issue. In this thesis, the digital signal processing (DSP) capabilities

of chosen microcontroller are investigated. The end goal is to use the mi-

crocontroller to create a time-of-flight algorithm and find an accurate pipe

wall thickness. There are some limitations to the DSP capabilities of the

microcontroller, but it is nevertheless possible to create a good time-of-flight

algorithm. The finite impulse response (FIR) filter implemented on the mi-

crocontroller showed promising results with very low power consumption and

memory usage. A software test bench was created to aid in the development

process of the algorithm.
