Finite word-length effects in multirate two-channel quadrature mirror filter (QMF) banks are presented. Aliasing cancellation, amplitude and/or phase distortions, and the perfect-reconstruction property due to finite-precision effects are investigated. A finite-precision model is applied to several types of QMF banks and the results are reported. © 1998 IEEE.

Founded in 1988 as the first private institution of higher education in the United Arab Emirates and the Gulf region, Ajman University (AU) is now being recognized as an emerging leader on the global academic map.

The 2020 QS World University Rankings lists AU in the top 800 universities globally and among the top 10 worldwide for international students and faculty! The &ldquo;Top 50 Under 50&rdquo; QS Rankings names AU as one of the top 150 young universities in the world. Even our distinct location in the Dubai/Sharjah/Ajman corridor is ranked by QS as the 61st best student destination on the planet. Recently, Ajman University earned Five QS Stars in three ratings categories -- Social Responsibility, Inclusiveness and Learning Environment. We also garnered Four QS Stars for both Teaching and Internationalization.
