采样带宽太低，没记错的话只有2.56Mbps吧下图是一个典型的RTLSDR电视棒幸运的是，sdrplay社区发现了一颗新星的芯片模组（msi2500/msi001）,这两颗芯片同样来自于电视棒，但是是更新的电视棒芯片

RTL-SDR成本价格最低，但和采用MSI2500+MSI100组合的SDRPlay相比，性能有点跟不上。从某宝上面上找了MSI2500+MSI100套片成15RMB不到，由极高的诱惑力。

要用操作系统的是用msi001 和 msi2500的组合芯片，msi2500负责摸数转换和IQ解调，通过USB和电脑通信，这个设计只用了msi001一颗芯片，负责AD转换和解调的是STM32，就不需要了
