| Nuts
and Bolts of the ΔΣ Converter: ΔΣ converters are ideal for
converting signals over a wide range of frequencies from DC to several
megahertz with very high resolution results. In a ΔΣ ADC, the input signal
is oversampled and then filtered by a digital/decimator filter. In this
video we will gain an understanding of the ΔΣ converter by exploring the
basic topology and functions of modulator and digital/decimator filter.
