dc.description.abstractThis paper presents a software based sigma-delta converter. The proposed A/D converter represents a lowcost and flexible digitalization solution that can be used in a large number of applications. The proposed discrete A/D converter tasks, that are performed by a microcontroller, include: digital filtering, oversampling, noise shaping and decimation. A simple implementation of the digital filtering is easily implemented by counting the number of high and low pulses contained in the feedback bit stream generated by the microcontroller. The first part of the paper contains an overview of the main characteristics of sigma-delta converters, the second part includes a brief description of the proposed sigma-delta converter, hardware, software and implementation details, and the last part will include simulation and experimental results.pt_PT
