band-pass sample

基本解釋

AimTo use the common sample frequency in low speed to the sample of band-pass signals of multiple different frequency point in full frequency rage.
目的用公共的低速採(cǎi)樣頻率對(duì)全頻段內(nèi)許多不同頻點(diǎn)的帶通信號(hào)進(jìn)行採(cǎi)樣。
Aiming at data acquisition of radar echo signal with low SNR, IF band-pass sampling concept is proposed. High-speed acquisition card PCI_9820 is used to sample in real-time and store data.
針對(duì)低信噪比的雷達(dá)廻波信號(hào)數(shù)據(jù)採(cǎi)集，文中給出了中頻帶通採(cǎi)樣方案，竝選用PC I_9820高速採(cǎi)集卡實(shí)時(shí)採(cǎi)集和存儲(chǔ)數(shù)據(jù)。
