In a world of digital electronics, there are still necessary functions for analog circuits, especially filters. When real-world signals are digitized or synthesized, for example, analog filters are ...

Active filters and advanced signal processing techniques are at the forefront of modern electronic system design, enabling precise manipulation of analogue signals for a variety of applications. Owing ...

In the last edition of Don’t Fear the Filter, we built up two examples of the simplest and most-used active filter of all time: the two-pole Sallen-Key lowpass. This time, we’re going to put two of ...

MIRUS International has launched its new, high performance LINEATOR Advanced Universal Harmonic Filter (AUHF) that matches the performance of Active Front Ends (AFE) or Active Harmonic Filters (AHF).

Active filters are ubiquitous in electronic design today, performing signal-frequency manipulation and conditioning for audio, IF (intermediate frequency), and digital-signal processing. The success ...

Logic Noise is an exploration of building raw synthesizers with CMOS logic chips. This session, we continue to abuse the 4069UB as an amplifier. We’ll turn the simple unity-gain buffer of last session ...

The EPCOS PQSine™ series of active harmonic filters from TDK Corp. are designed to optimize power quality. The modular filter systems are designed for 3-phase networks with and without neutral ...
