Alligator Technologies introduced its new USBPBP-S1, a USB-controlled single channel programmable signal conditioning instrumentation amplifier and band pass filter. Extremely configurable in a wide ...

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 ...

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.
