In part 1, we started to make some intuitive connections between near-Nyquist sampling, the addition of close-frequency sines, and how those signals would interact with perfect LP filters. Let's put ...

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 ...

Sampling a signal causes the original signal spectrum (blue) to create sum (purple) and difference (red) frequencies around the sampling frequency, fS. When the difference signals fall into the ...

n Part 3 of our CTSD precision ADCs article series, we will highlight the alias free nature of CTSD ADCs, which improves the immunity to interferers without any added peripheral design. Part 1 ...
