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 ...

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.

The CHPFL Series high-pass filters come encased in rugged SMA housings designed for use in test equipment and general lab apps. Five models with frequency ranges from DC to 100 MHz through 1 GHz are ...

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 ...

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.

Seoul National University College of Engineering announced that a research team led by Prof. Sung-Hoon Ahn of the Department ...
