Previous articles in Planet Analog make mention of the “aliasing effect.” Most EEs agree in the importance of the aliasing effect as a noise source and take for granted that anti-aliasing filters are ...

Suppose you take a few measurements of a time-varying signal. Let’s say for concreteness that you have a microcontroller that reads some voltage 100 times per second. Collecting a bunch of data points ...

Housed in standard industrial enclosures, Signal Conditioning System (SCS) packages from Microstar Laboratories work with data-acquisition processor (DAP) boards inside networked PCs to eliminate all ...

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 ...

The term ‘aliasing’ is a general term applied to signal processing. It refers to an effect that causes different signals to become indistinguishable (or aliases of one another) when sampled. In ...
