通信含义上,接收机解调过程产生的新频率信号对其他系统的干扰。
...体其实有无数个固有谐振频率,AT切的有1,3,5,7等奇次谐波,SC的还有A,B,C三种振荡模式,此外还可能有我们称之为杂散(SPURIOUS)的..

第一,有一些人考虑整个通道作为杂散。
First, there are those who consider the whole passage as spurious.
除了大功率,由于低相噪和低杂散,该放大器也提供改进的性能。
In addition to high power, the amplifiers also provide improved performance due to very low phase noise and spurious.
由于高阻电路容易拾取杂散的辐射噪声,所以需要采取屏蔽措施。
Shielding is required because high impedance circuitry is susceptible to pickup of spurious radiated noise.
