In the design phase, a whole Top-Down analysis and module design was done, and finally the circuit of the Baseband module was realized and tested.
接着对系统进行了顶层设计并逐步细化，最终完成了基带电路板的制作与调试。

The errors are classified according to their frequency. The amplitude and phase errors of the LFM signal generators using quadrature modulation technology are mapped into baseband.
