[Summary of tips] This application note covers two topics in digital signal processing and metering, namely the Fast Fourier Transform (FFT) and the sigma-delta analogue-to-digital converters (SD ADC). Firstly, the FFT is a mathematical technique for transforming a time-domain digital signal into a frequency-domain representation of the relative......
