For those who don’t design audio circuits full-time, a Bessel filter is a linear, passive bandpass filter that preserves waveshapes of signals that are within the range of the filter’s pass ...

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.

To demonstrate this, [FesZ] used an online tool to design a bandpass filter for ADS-B signals. He designed two filters, one using standard FR4 substrate and the other using the more exotic PTFE.

Kyocera AVX has released two new series of compact, thin-film band-pass filters engineered to provide excellent RF performance in a wide range of high-power applications with crowded PCBs.

A bandpass filter used to process audio and video signals by mixing the original with a delayed signal. Comb filters allow selected frequencies to pass while blocking their harmonics and all other ...

Support control electronics allows end user's camera to capture up to 2,000 wavelengths/frames per second. The AOTF HSI provides the complete spectrum of each pixel to the end-user for further ...

These emission filters are also designed for 5 degrees AOI, as are many of the modern widefield systems, to reduce internal reflections. The Chroma et525/50m bandpass emitter meets all of the ...
