                   Overview
               „ Early days of computing, data was 
                numerical and textual.
               „ Today, many other forms of data: voice, 
                music, speech, images, computer graphics, 
                etc.
               „ Each of these types of data are signals. 
               „ Loosely defined, a signal is a function that 
                conveys information.
                                                            5
                    Relationship of Signal 
                    Processing to other fields
               „ As long as people have tried to send or 
                 receive through electronic media : 
                 telegraphs, telephones, television, radar, 
                 etc. there has been the realization that 
                 these signals may be affected by the 
                 system used to acquire, transmit, or 
                 process them.
               „ Sometimes, these systems are imperfect 
                 and introduce noise, distortion, or other 
                 artifacts.
                                                            6
               „ Understanding the effects of these 
               systems and finding ways to correct them is 
               the fundamental of signal processing.
                „ Sometimes, these signals are specific 
               messages that we create and send to 
               someone else (e.g., telegraph, telephone, 
               television, digital networking, etc.).
                
               „ That is, we specifically introduce the 
               information content into the signal and 
               hope to extract it out later.
               „ Sometimes, these man-made signals are 
                encoding of natural phenomena (audio 
                signal, acquired image, etc.), 
               „ but sometimes we can create them from 
                scratch (speech generation, computer 
                generated music, computer graphics).
               „ Finally, we can sometimes merge these 
                technologies together by acquiring a 
                natural signal, processing it, and then 
                transmitting it in some fashion.
