AAF has various meanings in the Signal category. Discover the full forms, definitions, and usage contexts of AAF in Signal.
An anti-aliasing filter is a filter used before a signal sampler, to restrict the bandwidth of a signal to approximately satisfy the sampling theorem. Since the theorem states that unambiguous interpretation of the signal from its samples is possible when the power of frequencies above the Nyquist frequency is zero, a real anti-aliasing filter can generally not completely satisfy the theorem.
SignalAn anti aliasing filter is a low pass filter used before a signal sampler, to restrict the bandwidth of a signal to approximately satisfy the sampling theorem.
