If we want to take samples of some analog waveform, as in doing analog to digital conversions at some particular conversion rate, there is an absolute lower limit to the rate of doing conversions ...

In An Approximation to the Aliasing Effect, Part 1: The Origin I revisited some basic concepts about the aliasing effect, though I did it from a more visual than theoretical perspective. This second ...

With the growing use of multiple video formats, a fundamental understanding of sampling rate conversion will provide insight into the quality and operation of format converters. However, before ...

A look at the Nyquist sampling theorem. How to deal with aliasing by attenuating signals using low-pass filters (i.e., an antialiasing filter, or AAF). AAF requirements for different ADCs. A deep dive ...

The relationship between a signal’s constituent frequencies and the sampling rate used to quantize them is fundamental. As shown in Figure 1, sampling a signal that has a given spectrum creates a ...
