OBJECTIVES:

 

  • To learn discrete Fourier transform and its properties
  • To know the characteristics of IIR and FIR filters learn the design of infinite and finite impulse response filters for filtering undesired signals

 

  • To understand Finite word length effects
  • To study the concept of Multirate and adaptive filters

UNIT I DISCRETE FOURIER TRANSFORM 

Discrete Signals and Systems- A Review – Introduction to DFT – Properties of DFT – Circular Convolution – Filtering methods based on DFT – FFT Algorithms –Decimation in time Algorithms, Decimation in frequency Algorithms – Use of FFT in Linear Filtering.

UNIT II IIR FILTER DESIGN 

Structures of IIR – Analog filter design – Discrete time IIR filter from analog filter – IIR filter design by Impulse Invariance, Bilinear transformation, Approximation of derivatives – (LPF, HPF, BPF, BRF) filter design using frequency translation.

UNIT III FIR FILTER DESIGN 

Structures of FIR – Linear phase FIR filter – Fourier Series – Filter design using windowing techniques (Rectangular Window, Hamming Window, Hanning Window), Frequency sampling techniques – Finite word length effects in digital Filters: Errors, Limit Cycle, Noise Power Spectrum.

UNIT IV FINITE WORD LENGTH EFFECTS 

Fixed point and floating point number representations – ADC –Quantization- Truncation and Rounding errors – Quantization noise – coefficient quantization error – Product quantization error – Overflow error – Roundoff noise power – limit cycle oscillations due to product round off and overflow errors – Principle of scaling

UNIT V DSP APPLICATIONS 

Multirate signal processing: Decimation, Interpolation, Sampling rate conversion by a rational factor – Adaptive Filters: Introduction, Applications of adaptive filtering to equalization.
