Towards More Efficient DSP Implementations: An Analysis into the Sources of Error in DSP Design

Tinotenda Zwavashe, Rudo Duri, Mainford Mutandavari

This paper aims to highlight the commonly encountered sources of errors in Digital Signal Processing applications. Digital signal processing now finds application in a variety of fields due to the simplicity of handling digital signals and many more advantages which come with digital signals over analogue signals (as shall be specified in the introduction). As designers and scholars become more aware of the sources of errors in the processing of digital signals then the efficiency and accuracy of computed results increases. The knowledge also, in some way, aid in the efficient utilization of the available system resources as people become more aware of the overall system being required and the performance characteristics expected while taking down erroneous values to their minimum possible levels. The approach used will take into account the architecture of the Digital Signal Processing system and then analyze the causes of erroneous output from the system by taking into consideration the building blocks of the DSP system.
