spurious frequency

The geophone spurious frequency is modeled as the resonance of the planer motion of spider spring by carrying moving mass.

检波器的假频是借助支撑运动体对支座弹簧的水平运动作为谐振来模拟的。

Direct Digital Frequency Synthesis ( DDS ) technique is introduced and its spurious error is mainly studied.

介绍了直接数字频率 合成技术 以及分析其杂散误差,对相位截断误差和幅度量化误差进行了傅立叶级数分析研究.

The spurious lines caused by those sources can be classified into different sets according to the greatest common divisor of the DDS frequency control word ( FCW) and 2 N, where N is the word length of the DDS phase accumulator.

由此产生的杂散谱可根据DDS的频率控制字和2N的最大公约数进行分类，N是DDS相位累加器的字长。

This paper discusses three types of interference: spurious emission, intermodulation and block distortion. It also innovates fractional frequency reuse from physical layer and data link layer.

本文讨论了三种主要的干扰类型&杂散干扰、互调干扰和阻塞干扰，并结合物理层与数据链路层对规避干扰的分数频率复用法进行了创新。

数字地震检波器假频机理的研究

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。
