TAILIEUCHUNG - DISCRETE-SIGNAL ANALYSIS AND DESIGN- P34

DISCRETE-SIGNAL ANALYSIS AND DESIGN- P34:Electronic circuit analysis and design projects often involve time-domain and frequency-domain characteristics that are difÞcult to work with using the traditional and laborious mathematical pencil-and-paper methods of former eras. This is especially true of certain nonlinear circuits and sys- tems that engineering students and experimenters may not yet be com- fortable with. | THE HILBERT TRANSFORM 151 expensive. Receivers very often combine the phasing and filter methods in the same or different signal frequency ranges to get greatly improved performance in difficult-signal environments. The comments for the SSB transmitter section also apply to the receiver and no additional comments are needed for this chapter which is intended only to show the Hilbert transform and its mathematical equivalent in a few specific applications. Further and more complete information is available from a wide variety of sources . Sabin and Schoenike 1998 that cannot be pursued adequately in this introductory book which has emphasized the analysis and design of discrete signals in the time and frequency domains.
