In the UAV telemetry& control system, it is required that the numerical control oscillator ( NCO) having high frequency resolution and small spurious signal.
无人机的测控系统要求数控振荡器(NCO)的频率分辨率高、相位噪声低、杂散小。
To satisfy the PCM telemetry baseband equipment performance requirements of the ground system of Beijing TTC& M earth station, a new design technique of digitized synthesizer whose output frequency can be changed continuously ( resolution: 1Hz) is proposed in this paper.
针对北京TTC&M站地面编码遥测基带设备的性能指标要求,设计了一种高性能数控连续可调频率合成器,应用于航天测控系统中。
