Editor’s note: I came across this excellent tutorial article on Digital Filter Design and I thought it would be an excellent guide for novices as well as seasoned veterans. I want to thank William H.

Air Force Research Laboratory scientists recently patented a new tunable radio frequency (RF) filter design. The new design is for a smaller, lighter, less expensive device that requires much less ...

In the recent blog article “Our wireless world – how Wi-Fi 6 will seamlessly integrate with 5G to keep us connected,” David Haynes from our Customer Support Business Group (CSBG) explained how this ...

In part 1 of this pair of articles, we ran SPICE noise simulations on a simple second order lowpass filter. We saw that there is something fundamental about the ‘hold’ that the filter’s capacitor ...

Murata Manufacturing has begun mass production and commercial shipment of the first high-frequency filter to use XBAR technology. First high-frequency filter to use XBAR technology goes into ...

Listen to the pop, sizzle, and hum. Look at the bars and wavy lines. These and other characteristics of electromagnetic interference (EMI) are very familiar. RF energy is radiated from a culprit ...

Binary search, a decrease-and-conquer approach, plays an important role in testing today�s low-pass filters. When testing a low-pass filter, generally you have to use an arbitrary waveform generator ...

In part one of a two part series, we unpack why digital equalizers and filters sound characteristically harsh. By Christian Luther. Digital filters (for instance, in equalizer plugins) traditionally ...
