| Abstract: | A kind of multi functional tone frequency signal acquisition and processing system which is composed of 386 microcomputer and data acquisition card is reported. The design of hardware and software are described. Making use of this system, tone frequency signal is digitized first,then a various of modulation and demodulation are completed. The middle process and final results can be showed dynamically on the screen. This system can be provided with higher character and lower price. |
