band sample造句

• The delay chip , whose delay precision can be 10ps , wide band sample - hold amplifier ( sha ) , and high speed and precise analog / digital conversion ( adc ) are used in the system
  能够对5mhz以下的信号进行随机采样、波形显示、频谱分析，还能够对采集的波形数据进行存储、共享。
• The architectures of the receiver are rf pass band direct sampling and if pass - band sampling with high - speed analog to digital converter after rf to if conversion . the first kind of architectures is hard to realize because of the requisition of devices is too high
  软件无线电接收机分为射频直接带通采样和将射频信号变换到中频后再进行带通采样，前者实现较难，对器件的要求太高，然后进行各种数字处理。
• Compared to the analogy or the base - band sampling solution , this structure not only enhanced the system mobility , the flexibility and stability , but also reduced the cost , moreover it may be a public platform , which realize multi - purpose and multi - service patterns communication signal despread and demodulation , has fully reflected the thought of software radio
  与采用模拟或基带采样解扩解调方式相比,这种结构既增加了系统的机动性、灵活性和稳定性,同时价格大幅下降,而且可以作为一个公用平台,实现多功能、多制式通信信号解扩解调,充分反映了软件无线电的思想。
