This course serves as a bridge to understanding the relationship between the Analog world and its Discrete-Time representation in digital computers. Digital Signal processing is covered with emphasis on the relationship between continuous-time and discrete-time systems in the time and frequency domains. Practical aspects of digital filter design and implementation structures are discussed and the use of stochastic models to model quantization effects in digital signal processing is introduced. Real world applications of Digital Signal Processing are analyzed to provide insight into the application of these techniques. Clarity in important DSP concepts is provided using MatLab for exercises and experiments in digital signal processing techniques.
