WebFeb 10, 2015 · Using the delta-sigma (ΔΣ) modulator, the ADC converts the input into a digital pulse stream with a 1’s density proportional to the input divided by the reference. Let’s take a practical example to show how the digital filter converts the pulse stream into a data word representing the conversion. (For more on how the delta-sigma ADC is ... WebFigure 1-1. Digital filtering. The process of converting an analog signal into digital form is performed by sampling with a finite sampling frequency fs. If an input signal contains frequency components higher than half the sampling frequency (fs/2), it will cause distortion to the original spectrum. This is the reason why it is first necessary ...
