Design and Implementation of Maximally Decimated Polyphase Filter Bank for Power and Delay Efficient Digital Hearing Aids
Sudhi Sudharman, T. S. Bindiya · 2019
A computationally efficient maximally decimated filter bank core, suitable for digital hearing aids is designed and implemented in this work. The main advantages of the proposed design method are that the computational complexity and delay are less than that of the other filter bank based architectures in the literature. To reduce the hardware complexity of the filter bank core, filter coefficients are optimized and are implemented multiplier-free.
