Abstract： A practical design of real-time data acquisition system of high-accuracy
was introduced in this paper. This system is based on USB, and sampling precision can
reach 16-bit. It is low cost, easily and conveniently developed, and has high
practicality and outstanding expansibility. It can be widely used in many kinds of signal
processing systems. By the introducing in the paper, a kind of practical design of
developing equipments based on USB to readers as well.
