Figure 30-8 Advanced signal processing. After a signal has been transduced (see Fig. 30-3 ) and initially processed (see Fig. 30-4 , Fig. 30-5 , Fig. 30-6 , and Fig. 30-7 ), it can then be further analyzed, converted into data streams for transfer and storage, encoded for security, and linked to other signals for presentation to the user as information.
