WebAn anti-aliasing filter (AAF) is a filter used before a signal sampler to restrict the bandwidth of a signal to satisfy the Nyquist–Shannon sampling theorem over the band of interest. Since the theorem states that unambiguous reconstruction of the signal from its samples is possible when the power of frequencies above the Nyquist frequency is zero, a brick wall … WebThe traditional design of bandpass filters in the UV involves induced transparency in a metal (usually Al or Ag). These filters are very inexpensive to produce, comprising only a handful of layers and providing high blocking over the entire visible wavelength range. The disadvantages include low transmission (often under 20%) and spectral edges ...
