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 ...

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 ...

This amplifier-based IC implements dual low-pass filters with matched response at cutoff frequencies up to 10 MHz. To build active filters for high-frequency RF applications, designers may construct ...

A micromachined spin-wave filter shows how future radios could tune across the 6G spectrum using a single magnetic bias. Study: Spin-wave band-pass filters for 6G ...

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.
