AWR® has announced that Nuhertz Filter (a filter synthesis and analysis software from Nuhertz Technologies®) can be integrated with AWR's Microwave Office® high-frequency design suite. The company ...

Salisbury, MD. K&L Microwave announced it has developed a family of miniature high-pass filters with cutoff frequencies of 6 to 18 GHz. The filters guarantee rejection of 45 dB at 1/2 the 3-dB cutoff ...

Several manufacturers offer op amp-based filter design tools [1-3]. Some tools choose off-the-shelf capacitor values, but others select non-standard ones. The option to alter passive component ...

Many sensors have a small analog signal that rides on top of a larger dc pedestal. For these circuits (Fig. 1), the signal must be ac coupled and amplified before it’s digitized. The feedback of an ...

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.
