Output of SS PLL may be processed to reduce interference. For example, a sinusoidal spreading signal may be used to spread the output of the SS PLL. A notch filter tracks the frequency of the output of the SS PLL to steer the notch in the filter to the instantaneous frequency output from the SS PLL, thus allowing the notch filter to be placed in the path of signals that have unwanted leakage from the SS PLL."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for cancellation of interference from a spread spectrum phase lock loop","description":"Systems and methods for provided for reducing interference caused by leakage of signals generated by a spread spectrum phase lock loop (SS PLL).
