NTT Corp. (NTT) and Okayama University have developed a solution to the increasing problem of IoT signal interference by creating a topological ultrasonic circuit. Claimed as the first of its kind, ...

Nyquist-sampling theory lies at the heart of today's digital-communications systems. It requires that data-conversion systems include antialiasing input filters. Designers need to understand the ...

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 ...
