For those who don’t design audio circuits full-time, a Bessel filter is a linear, passive bandpass filter that preserves waveshapes of signals that are within the range of the filter’s pass ...

We bet when [devttyS0] made his latest video about RF filter design (YouTube, embedded below), he had the old saying in mind: in theory, there’s no difference between theory and practice ...

Understand the need for input filters and the effects input filters may have on converter responses. Design properly damped single and multi-section filters to meet the conducted EMI attenuation ...

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 ...

In this paper, we first review in detail the basic building blocks of reconfigurable devices, essentially, the field-programmable gate arrays, then we describes a high-speed, reconfigurable Systolic ...

Researchers in Copenhagen have created a market-ready anti-pollution filter designed to quickly remove nitrogen dioxide (NO2) and particulate matter from inside vehicles. They say the Airbubbl is ...

The Neewer ND2-32 True Colors Hard Stop Variable ND Filter features a ‘hard stop’ to help you avoid the risk of X-shaped ...

This paper presents the design and performance of a key RF circuit necessary for the realization of a reconfigurable, integrated RF front-end: a tunable frequency, selectable bandwidth, on-chip, “SAW ...
