2.10 SUMMARY
A brief review of some of the essentials of signal processing techniques were described in this chapter. In particular, some of the important concepts covered in this chapter include:
- Continuous Fourier transform
- Spectral leakage effects
- Convolution, sampling, and aliasing issues
- Discrete-time Fourier transform and z-transform
- The DFT, FFT, DCT, and STFT basics
- IIR and FIR filter representations
- Pole/zero and frequency response interpretations
- Shelving and peaking filters, audio graphic equalizers
- Down-sampling and up-sampling
- QMF banks and alias-free reconstruction
- Discrete-time random signal processing review.
