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.
目的用公共的低速采樣頻率對全頻段內(nèi)許多不同頻點的帶通信號進行采樣。
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.
針對低信噪比的雷達回波信號數(shù)據(jù)采集，文中給出了中頻帶通采樣方案，并選用PC I_9820高速采集卡實時采集和存儲數(shù)據(jù)。
