Description
technical field
[0001] The invention relates to a data acquisition device, in particular to a multi-channel data acquisition device based on the PCIE protocol. Background technique
[0002] The current digital signal processing technology is developing at a rapid pace, and the design concept of "software radio" is increasingly recognized by the industry. The core of the "software radio" technology is to move the analog-to-digital conversion closer to the radio frequency antenna, that is, to apply more digital signal processing technology. At present, the basic theory of digital signal processing has been developed very maturely, which can make better use of these advanced technological achievements and improve the overall quality of the system.
[0003] However, the core of the "software radio" technology needs the support of high-speed data acquisition devices, because according to the Nyquist theorem, the closer the analog-to-digital conversion is to the radio frequency a...
