Abstract
To fully exploit the benefits of using an sub adaptive filter (SAF), an almost alias free SAF structure is proposed. The inter band aliasing is removed from the sub band signal using a band width increased filter.SAF overcomes the disadvantages of full-band structure like high computational cost, slower convergence rates.
