| Abstract: | Based on the foundmental theory and technology of signal gethering and processing,combining computer programing and indicated interface cards, a multi functional compute systen is established. The system can be viewed as a virtual instrument which has the functions of signal processing and functions of signal generater. As a signal processor, the system can perform signal fikering, programed data analysis, signal gethering and display; as a signal generator, the system can generate signals with different types, frequencies, phases and megnitudes. |
