Normalized frequency (signal processing)
open-in-new
<p>In <a href="/facts/Digital_signal_processing/PEG7azr8">digital signal processing</a> (DSP), a normalized frequency is a ratio of a variable <a href="/facts/Frequency/QUSbPaW8">frequency</a> ( f {\displaystyle f} ) and a constant frequency associated with a system (such as a <i><a href="/facts/Sampling_rate/xxck7aLN">sampling rate</a></i>, f s {\displaystyle f_{s}} ). Some software applications require normalized inputs and produce normalized outputs, which can be re-scaled to physical units when necessary. Mathematical derivations are usually done in normalized units, relevant to a wide range of applications. </p>
