摘要： A method for applying spread spectrum noise reduction techniques to USB specifically USB2.0 communications systems includes the step of generating a base (seed) frequency for the USB system, modulating the base (seed) frequency with a spread spectrum (SS) characteristic, and utilizing (as-is, not modified) the existing ASIC that multiplying the now modulated base (seed) frequency to generate the USB standard frequency signaling rate of 480 MHz with the SS characteristic within the USB standard specification for frequency deviation.

摘要： An electronic system that partially or perhaps even fully mitigates the effects of EMI by having a dedicated antenna circuit for carrying an antenna signal that is not used for signal processing in the functional circuit, but is instead used to emit electromagnetic radiation that at least partially offsets EMI emitted by the operation signal of a functional circuit. An antenna signal generation circuit generates the antenna signal and asserts the antenna signal on the antenna circuit. The ante a signal has the characteristic such that when the antenna signal is applied to the antenna circuit, the resultant emitted electromagnetic radiation at least partially offsets electromagnetic interference emitted by the functional circuit.
摘要翻译：一种电子系统，其部分或甚至可以通过具有用于承载不用于功能电路中的信号处理的天线信号的专用天线电路来部分或甚至完全减轻EMI的影响，而是用于发射至少部分抵消的电磁辐射由功能电路的操作信号发出的EMI。天线信号发生电路产生天线信号，并在天线电路上断言天线信号。信号具有这样的特征，使得当天线信号被施加到天线电路时，所产生的发射的电磁辐射至少部分地抵消由功能电路发射的电磁干扰。
