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 ...

Try looking up Fast Fourier Transforms. That will convert your signal to an array of frequency magnitudes, you can attenuate the lower frequencies, and then reverse-FFT back to the filter signal.

Reportedly the thinnest available, the company’s 1005-size thin-film band-pass filter measures 0.3-mm thick. Overall, the device measures1.0 mm x 0.5 mm and targets portable applications including ...

Cellular telephone technology takes advantage of a large number of frequency bands to provide ever-increasing bandwidth for mobile use. Each of those bands needs a filter to keep its signals separate ...

Determine the center frequency, maximum gain and bandwidth for the filter in the figure shown. The quality factor of the filter is equal to With Q=4.16, the bandwidth for the filter is equal to Source ...

SDRs have been a game changer for radio hobbyists, but for ham radio applications, they often need a little help. That’s especially true of SDR dongles, which don’t have a lot of selectivity in the HF ...

DELTA’s innovative family of linear variable filters is extended with a sixth type – the best ever linear variable VIS band pass filter (LVVISBP). DELTA has lifted the application range of variable ...

Measuring 1.5” x 0.5” x 0.4”, the surface-mount AE1706L8769 lumped-element low-pass filter is suitable for applications at L-band frequencies. Features include a cutoff frequency is 1,706 MHz, an ...

[Ryan] wanted a spectrum analyzer for his audio equipment. Rather than grab a micro, he did it the analog way. [Ryan] designed a 10 band audio spectrum analyzer. This means that he needs 10 band-pass ...
