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 ...

Cypess' Dave Van Ess describes three problems associated with ac coupling a small signal riding on a large dc potential to a signal-conditioning amplifier, with solutions. Many sensors have a small ...

A filter that blocks low frequencies and allows higher frequencies to pass through. Such filters are used in devices such as POTS splitters that direct phone and DSL signals to different lines.

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 ...

The CHPFL Series high-pass filters come encased in rugged SMA housings designed for use in test equipment and general lab apps. The CHPFL Series high-pass filters come encased in rugged SMA housings ...

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.
