Multirate Digital Signal Processing
Prentice-Hall, 1983, ISBN 0-13-605162-6.
This book is the only real reference for filter banks and multirate systems, as opposed to being a tutorial.
Peter Kootsookos notes: this book is most certainly an excellent book on multi-rate signal processing, but it came out right before perfect reconstruction filter banks hit the streets. Multirate Systems and Filter Banks by P. P. Vaidyanathan covers this issue.
