Encapsulating DASP Technology

At present there are no external obstacles preventing beneficial exploitation of the digital alias-free signal processing technology on a relatively large scale. The existing microelectronic elements could be used for developing the hardware needed for that and there does not seems to be any problems with creating software. Actually this is not exactly correct. There are problems that complicate widespread application of the signal processing technology discussed in this book. Basically these are related to the fact that considerable expertise is required to be successful in this area and it is not very easy to acquire this. Substantial investments in terms of effort, time and money are needed to gain knowledge and experience sufficient to achieve really significant positive results. It is not realistic to expect that building such expertise can be done in many places quickly. A more rational and practical approach to widening the application field for this technology is based on the idea that the benefits in this area could be gained more easily by developing and exploiting application-specific subsystems for digital aliasfree signal processing. That clearly has to be done by embedding them in various larger IT systems operating as usual. This approach is discussed in this chapter. Among the gains immediately achievable in this way, widening of the digital domain in the direction of higher frequencies, simplification of data compression, complexity ...
