Resumo

Most of applications on nuclear experiments require measurements using an analog-to-digital converter (ADC). In the case of the Multi-Channel Analyzer (MCA), the aim is to implement a digital version of the analog chain with a good pulse height analysis. However, the higher the desired accuracy and sample frequency, the higher the data acquisition system cost. This report shows the application of multi-rate techniques to increase the resolution of measurements with lower cost digital data acquisition systems.
