A technical paper titled “Compact and wideband nanoacoustic pass-band filters for future 5G and 6G cellular radios” was published by researchers at Northeastern University. “Over recent years, the ...

Can you buy a working radar module for $12? As it turns out, you can. But can you make it output useful information? According to [Mathieu], the answer is also yes, but only if you ignore the ...

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.

Wideband filters with bandwidths in excess of an octave can be created by cascading a high-pass filter and a low-pass filter. In this design idea, nine-pole high-pass and low-pass filters have been ...

ERI will introduce a new FM Band-Pass Filter product line at the convention this week, aimed at IBOC and low-power analog FM users. “The filter series is designed for use as a band-pass filter for ...

Most oscilloscopes are fitted with filters to help improve measurement by reducing overall noise in an acquisition to improve signal-to-noise ratio (SNR). Even the most basic oscilloscopes include an ...

We're all familiar with low-pass filters, high-pass filters, band-pass filters, band-stop filters and other filter types, but the all-pass filter is perhaps less well known. All-pass filters have no ...
