A tutorial on multirate digital filter banks
Palghat P. Vaidyanathan · 2003
A number of topics in multirate digital signal processing, such as decimation and interpolation, polyphase structures, power-complementary and Mth band filters, and digital filter banks are reviewed. Maximally decimated digital filter banks are emphasized, and the problem of perfect reconstruction reviewed. The role of FIR (finite-impulse-response) lossless systems in this context is also reviewed.>
