The Design of Multi-channel Signals Source Based on FPGA

摘要

the multi-channel singals source that the structure is simple and flexible control is proposed in the ariticle .with FPGA and high-speed D/A as its core. The choice of parts of an apparatus, hardware constitution and design of software of the gnals source are recommended here. Before the hardware designed.detailed theoretical analyses and quantitative , description for the key factors on effecting the precision of signal source were are given.and when debugging in hardware circuit is completed,on the base of analysis.errors estimation were verified with experimental results.
