Algebraic signal processing
open-in-new
<p>Algebraic signal processing (ASP) is an emerging area of theoretical <a href="/facts/Signal_processing/Npaja6zb">signal processing</a> (SP). In the algebraic theory of signal processing, a set of <a href="/facts/Filter_(signal_processing)/vydJCNle">filters</a> is treated as an (abstract) <a href="/facts/Algebra_(ring_theory)/8T8ulWJb">algebra</a>, a set of <a href="/facts/Signal_(electrical_engineering)/41YqUJ8c">signals</a> is treated as a <a href="/facts/Module_(mathematics)/jP0LIhFL">module</a> or <a href="/facts/Vector_space/M1pxMLx2">vector space</a>, and <a href="/facts/Convolution/PVPrdz9J">convolution</a> is treated as an <a href="/facts/Algebra_representation/1MaaEjqH">algebra representation</a>. The advantage of algebraic signal processing is its generality and portability. </p>
