All-Pass Filter Phase Shifters – John Dunn, Consultant, Ambertec, P.E., P.C. We're all familiar with low-pass filters, high-pass filters, band-pass filters, band-stop filters and other filter types, ...

Current‐mode all‐pass filters represent a crucial class of signal processing circuits that, by utilising current signals rather than voltage signals, offer inherent advantages in terms of integration, ...

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 ...

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.

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 ...

Many sensors have a small analog signal that rides on top of a larger dc pedestal. For these circuits (Fig. 1), the signal must be ac coupled and amplified before it’s digitized. The feedback of an ...

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 ...
