PHASE COMPARATOR USING UNDERSAMPLING

摘要

Systems and methods for utilizing universal frequency translators for phase detection and/or frequency detection. Phase and/or frequency detection can be utilized for comparing a higher frequency reference signal with a lower frequency local oscillator signal. Phase and/or frequency detection can also be utilized for phase locking and/or frequency locking. The systems and methods can be utilized to simultaneously down-convert a reference signal for phase and/or frequency comparison and/or for locking.
