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 ...

In this video, I explain some theories behind a low pass active filter circuit, then I built a simple active low pass filter using the LM358 opamp. I examined the filter’s behavior using the Siglent ...

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 ...

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 ...
