An input signal can be delayed to generate a delayed version of the input signal. Next, a phase difference can be detected between the input signal and the delayed version of the input signal. A phase noise level in the input signal can then be determined based on the detected phase difference. The measured phase noise level can then be used to suppress phase noise in the input signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Phase noise measurement and filtering circuit","description":"Methods and apparatuses for measuring a phase noise level in an input signal are disclosed.
