| Abstract: | In order to sample transient travelling wave, the design of a high-speed data acquisition system with the single-chip microcomputer DS80C320 is introduced. The forming method of fast speed address, the relation between high-speed A/D conversion and fast access, and the interface technique of PC bus are discussed in detail. This board is up to the standard of ISA bus, and can be used to sample the high-speed transient travelling wave. |
