Filter fans perform a critical task of cooling equipment within electrical enclosures while also protecting equipment from ingress of harmful dust, water, or other materials. Cooling is necessary to ...

Low-pass filters (LPFs) are fundamental components in modern electronic systems, serving to permit signals below a designated cutoff frequency while attenuating higher frequencies. Recent advances ...

To provide additional insight in the application and impact of precision in digital filter, examples of two practical digital applications are shown. The first example is an equalization of a small ...

Current‐mode all‐pass filters represent a crucial class of signal processing circuits that, by utilising current signals rather than voltage signals, offer inherent advantages in terms of integration, ...

The initial applications of single-use filtration products were for small-scale processes in laboratories where total process volumes were either quite small or exhibited low solids content. Today, ...

Brick wall filters are desirable in a number of audio, instrumentation and data acquisition applications. Creating these filters in the analog domain presents many cost and implementation challenges, ...

The field of applications and instrumentation that utilize laser sources is quickly advancing. For example, confocal and multiphoton microscopy, Raman spectroscopy, and flow cytometry all make use of ...

Graham Rideal of Whitehouse Scientific explains the importance of filter testing and offers some considerations with regards to choosing filter test methods. Filtration in the pharmaceutical industry ...

This article is part of the Ideas for Design Series: Vol. 3, No. 9. Many communications and sensor applications require a bandpass filter with wide bandwidth. This filter typically requires precision ...
