Low-pass filters (LPFs) are fundamental components in modern electronic systems, serving to permit signals below a designated cutoff frequency while attenuating higher frequencies. Recent advances ...

Do we really need another design tool for Sallen-Key filters? Aren’t there enough [i] [ii] [iii] [iv] [v] already? Obviously, you and I think that there’s something more to say on this topic, or you ...

Several manufacturers offer op amp-based filter design tools [1-3]. Some tools choose off-the-shelf capacitor values, but others select non-standard ones. The option to alter passive component ...

Binary search, a decrease-and-conquer approach, plays an important role in testing today�s low-pass filters. When testing a low-pass filter, generally you have to use an arbitrary waveform generator ...

To achieve high-precision measurements required for today’s advanced systems, maintaining low noise is essential. One effective solution is to have a voltage reference followed by a signal-flow-graph ...

My previous column described the Sallen-Key circuit for a low-pass filter. At times, you will not find a low-pass filter with the specifications you need in an anti-alias circuit, so you might decide ...

This monograph describes the theoretical and practical details of the design of a very linear phase-shift low-pass filter intended to remove noise and other irrelevant information above approximately ...

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 ...
