3IntroductionObjectives In this course we introduce techniques to process signals by digital computers.A signal can come from a number of different sources:filtered signal:reject disturbances.sonarDSPHardwareSoftwareradartransformed signal:detectioncompressionaudiovideo...
15Example: suppose we design a notch discrete time filter with transfer function with zeros and polesand sampling frequency Determine the magnitude of its frequency response in the continuous time domain.z-plane
16Solution: from what we have seen the frequency response is given by
