OBJECTIVES:
• To learn discrete fourier transform, properties of DFT and its application to linear filtering
• To understand the characteristics of digital filters, design digital IIR and FIR filters and apply these filters to filter undesirable signals in various frequency bands
• To understand the effects of finite precision representation on digital filters
• To understand the fundamental concepts of multi rate signal processing and its applications
• To introduce the concepts of adaptive filters and its application to communication engineering

We're excited to announce the launch of our new website! Visit NameWheelSpinner.com to explore its features and benefits.
