This audio noise filter circuit is a bandpass filter for audio frequency band. It filters unwanted signals that are lower or higher than the audio frequencies. It has 2 filters: a low pass filter and ...

Filtering switches and bandpass filter design constitute a crucial intersection in the development of modern radio frequency (RF) front-end architectures. Recent advances have concentrated on ...

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 ...

Bandpass Filters are used to selectively transmit a portion of the spectrum while rejecting all other wavelengths. Yutai Optics offers a wide variety of Bandpass Filters in a range of bandwidth ...

Once you fall deep enough into the rabbit hole of any project, specific information starts getting harder and harder to find. At some point, trusting experts becomes necessary, even if that ...

Fundamentals of analog filter design and linear circuits are covered in a book and kit of parts that are available on EIM Tech's site after a successful ~$108,000 Kickstarter campaign. EIM ...

The Colpitts oscillator is a time-tested design — from 1918. [The Offset Volt] has a few videos covering the design of these circuits including an op-amp and a transistor version. You can find the ...
