How any string instrument sounds depends on hundreds of factors; even the tiniest details matter. Seemingly inconsequential things like whether the tree that the wood came from grew on the north slope ...

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 low-pass filter is the most common filter found in data acquisition systems. Typically this type of filter is used to reduce analog-to-digital converter (ADC) aliasing errors and noise outside the ...

Knight Optical can offer infra-red interference longpass filters for use in Infrared Photography. We supply a range of infra-red interference longpass filters for a range of applications. All ...

Binary search, a decrease-and-conquer approach, plays an important role in testing today�s low-pass filters. When testing a low-pass filter, generally you have to use an arbitrary waveform generator ...

Any pointers to good resources on audio filters for WAV files (particularly low-pass filters) implemented in Java? I've found a goodly amount of resources on DSP and filters, but when it gets to ...

A filter which attenuates frequencies above its cutoff frequency (which is the point where the signal is 3 dB down). The slope of the filter is the rate of attenuation, i.e. 6, 12 or 24 dB per octave.
