Bandpass filters are indispensable in modern communication, radar, and imaging systems, serving to isolate desired frequency ranges while attenuating unwanted spectral components. Contemporary ...

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 ...

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 ...

不记得是哪个文章，有个读者说了一个滤波器，我只有搜索到了一个ADI的文档： 想起来了，是LMC6482的文章来着；滤波器其实有不少，但是也不多，其实就是滤波器的参数很多，没有一个是完美的，所以先聊聊这个滤波器的适用情况；其实主要是 “窄带滤波 ...

An electronic circuit that accepts a signal and filters out unwanted frequencies, allowing only a particular frequency or frequency range (band of frequencies) to reach the output side. See bandstop ...

Electronics Research Inc. will introduce a new FM bandpass filter at the NAB Show. It said the 940 Series is a compact model with an innovative form factor and construction to provide the smallest ...

With the narrowest bandwidths and highest transmission in the industry, Alluxa’s thin-film, ultra-narrow bandpass filters will optimize the performance of laser based systems. Ultra-narrow filters are ...

Switched-capacitor filters that are preset for a given bandwidth sometimes do not deliver the bandwidth or Q an application requires. By inverting the clock between two switched-capacitor bandpass ...

The BPC10087 bandpass filter offers less than 0.5-dB insertion loss at a 10-GHz center frequency, and less than 0.7-dB ripple over the 9.6- to10.4-GHz passband. The part also delivers a typical ...

One of the great things about the Hackaday community is how quickly you find out what you don’t know. That’s not a bad thing, of course; after all, everyone is here to get smarter, right? So let’s ...
