Low-pass filters in microwave engineering serve to transmit signals below a defined cutoff frequency while suppressing higher-frequency components. Design approaches span from classical lumped-element ...

How to design a simpler filter (or filter-like circuit) with a varying time constant dependent on what kind of waveform is fed to it. Discussions with some former coworkers have focused on how to ...

In this two-part “Filter Wizard”, we’ll look at some fundamental noise mechanisms in filters, using SPICE to illustrate the performance limits you can expect. We’ll concentrate on analog filters in ...

Noise is a common and pervasive problem in electronics design and debug. At one time or another, almost every designer and debugger of electrical circuits will spend some time dealing with ...
