What does PLV mean in UNCLASSIFIED
PLV stands for Phase Locking Value. It is a term used in the context of phase-locked loops (PLLs), which are electronic circuits that are commonly used in communications and signal processing systems.

Shorthand: PLV,
Full Form: Phase Locking Value
For more information of "Phase Locking Value", see the section below.
PLV Meaning
The Phase Locking Value is the value of the phase difference between the input and output signals of a PLL. When the PLL is in lock, the phase difference between the input and output signals is constant. The PLV is typically measured in degrees or radians.
How PLVs Work
PLLs work by comparing the phase of the input signal to the phase of the output signal. If the phase difference is too large, the PLL will adjust the frequency of the output signal until the phase difference is within a specified range. This process is called phase locking.
Applications of PLVs
PLVs are used in a variety of applications, including:
- Frequency synthesis
- Clock generation
- Signal conditioning
- Data recovery
Essential Questions and Answers on Phase Locking Value in "MISCELLANEOUS»UNFILED"
What is Phase Locking Value (PLV)?
Phase Locking Value (PLV) is a measure of the synchronization between two or more neural signals. It quantifies the extent to which the phase of one signal is locked to the phase of another signal. PLV is often used to assess the functional connectivity between different brain regions.
How is PLV calculated?
PLV is calculated by first extracting the phase information from the neural signals. This is typically done using Fourier analysis or Hilbert transform. Then, the cross-spectrum between the two signals is computed, and the PLV is defined as the average phase difference between the two signals over a specified frequency band.
What does a high PLV value indicate?
A high PLV value indicates that the two neural signals are strongly synchronized. This suggests that the two brain regions are functionally connected and that they may be engaged in the same cognitive or motor task.
What does a low PLV value indicate?
A low PLV value indicates that the two neural signals are not strongly synchronized. This may suggest that the two brain regions are not functionally connected or that they are engaged in different cognitive or motor tasks.
What are the applications of PLV?
PLV has a wide range of applications in neuroscience, including:
- Assessing the functional connectivity between different brain regions
- Identifying brain networks that are involved in specific cognitive or motor tasks
- Diagnosing neurological disorders such as epilepsy and schizophrenia
Final Words: PLV is a key parameter in the operation of PLLs. Understanding the concept of PLV is essential for designing and using PLLs in electronic circuits.
