Sampling technique allowing exclusion of antialiasingfilter
Yefim S. Poberezhskiy, Gennady Y. Poberezhskiy · Electronics Letters · 2000
It is shown that antialiasing filtering can be performed by a multichannel sample-and-hold amplifier with weighted integration, and a conventional antialiasing filter can be excluded when the weight function and number of channels are properly selected. This makes analogue-to-digital conversion less expensive and adaptable to various conditions.
