Comments on "Computationally Efficient Bank of Rectangular Digital Filters"
Ferdinand Liedtke · IEEE Transactions on Aerospace and Electronic Systems · 1976
In [1] a scheme for forming a rectangular FIR filter bank is described using only a few percent of the number of multiplications required by straightforward procedures. The sidelobe level suffers degradation. Attention is drawn to a different scheme published in [2] and [3] which needs even fewer multiplications without degradationvof the sidelobe level.
