LECTURE 09: RESAMPLING

• Objectives:
  
  
  • Learn how to change the sample rate of a signal
    
    
  • Understand how this can be implemented using time domain interpolation (based on the Sampling Theorem)
    
    
  • Understand how this can be implemented efficiently using digital filters
    
    
  • Introduction to digital filter banks

A good reference textbook on these topics is:

J.G. Proakis and D.G. Manolakis, Digital Signal Processing: Principles, Algorithms, and Applications, Prentice Hall, Upper Saddle River, New Jersey, USA, ISBN: 0-13-373762-4, 1996 (third edition).

The course textbook:

X. Huang, A. Acero, and H.W. Hon, Spoken Language Processing - A Guide to Theory, Algorithm, and System Development, Prentice Hall, Upper Saddle River, New Jersey, USA, ISBN: 0-13-022616-5, 2001.

has a detailed explanation of filter banks (sections 5.6 and 5.7).
