Three of the common filter topologies are Chebyshev, Butterworth, and Bessel. Which filter topology has the flatest response in the passband? Which filter topology has the steepest decline into the ...

Analog filters play an important part in electronic signal synthesis subsystems, providing functions such as antialiasing and noise filtering for A/D converters (ADCs), as well as “reconstruction” ...

Several people asked for more information about anti-alias filters used with analog-to-digital converters to remove unwanted signals. This column describes a filter-selection "gotcha," and includes ...

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 ...

If you are in any way connected with radio, you will have encountered the low pass filter as a means to remove unwanted harmonics from the output of your transmitters. It’s a network of capacitors and ...
