A bandpass allows a certain electrical signal to pass while filtering out undesirable frequencies. In a speaker bandpass, the mid-range speaker doesn’t receive tones meant for the tweeter or woofer.

With the narrowest bandwidths and highest transmission in the industry, Alluxa’s thin-film, ultra-narrow bandpass filters will optimize the performance of laser based systems. Ultra-narrow filters are ...

An electronic circuit that accepts a signal and filters out unwanted frequencies, allowing only a particular frequency or frequency range (band of frequencies) to reach the output side. See bandstop ...

LASER COMPONENTS supplies plasma deposited hard coated filters suitable for laser and imaging applications. A range of multi-bandpass filters are available from stock and can be specified with up to ...

a) Show that the RLC circuit in the figure above is also a bandpass filter by deriving an expression for the transfer function H(s). b) Compute the center frequency, ω o. d) Compute values for R and L ...

Filter design, be it active, passive, or switched capacitor, is traditionally a mathematically intensive pursuit. There are many architectures and design methods to choose from. Two methods of high ...

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.
