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 ...

Two-dimensional (2D) magnets, also known as magnetic van der Waals materials, have advantageous electrical and mechanical properties, such as antiferromagnetic or ferromagnetism. These properties make ...

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 ...

Tokyo, Japan — Designed specifically for GSM mobile phones, FDK Corporation said its new AMF1005L series of multilayer low-pass filters is the industry's smallest of its kind in a 1.0 x 0.5 x 0.3-mm ...

Listen to the pop, sizzle, and hum. Look at the bars and wavy lines. These and other characteristics of electromagnetic interference (EMI) are very familiar. RF energy is radiated from a culprit ...
