Together the book and CD-ROM form a learning system, which provides both investigated studies and the visualization of complex processes. A didactic concept is undertaken for microelectronics, computer technology and communication engineering, which deals with the visualization of signals and processes in addition to graphical programming of signal processing systems. Through the utilization of a professional and worldwide supported software of metrology and control engineering, useful applications can be developed, modified and optimized. Computer supported processing of real signals is made possible over the sound card and the parallel port. Over two hundred pre-programmed signal engineering systems and designed transparencies are provided.
