When you design an analog, lowpass, antialiasing filter, you would expect its gain amplitude to continuously decrease beyond the filter's cutoff frequency. For the most part, this assumption is a safe ...

A little while back, I presented a nearly-zero-offset Chebyshev lowpass filter. Two comments were made that must have seemed valid to their authors, but they were not. Figure 2 This change adversely ...

voltage. Often a passive single-pole RC filter will satisfy design requirements, but this approach typically suffers from several drawbacks including slow response time, noisy results, and having an ...
