Hidden oscillation

Hidden oscillation typically refers to a phenomenon in systems that exhibit oscillatory behavior that may not be immediately observable or detectable. This term can be applied in various fields, such as physics, engineering, biology, and even in social sciences, where systems can undergo oscillatory dynamics without clear or visible cycles. For example, in control systems or electronic circuits, hidden oscillations might occur due to nonlinearities or other complex interactions that mask the periodic behavior.

Nikolay V. Kuznetsov could refer to various individuals, as it is a relatively common name. However, without specific context, it's hard to pinpoint exactly which individual you're referring to. In academic or professional contexts, for example, he might be a researcher, scientist, or a professional in a certain field.

A Phase-Locked Loop (PLL) is an electronic circuit that synchronizes an output signal's phase and frequency with a reference signal. The PLL range typically refers to the frequency range over which the PLL can lock onto an input signal. This can be affected by several factors, including: 1. **Frequency Bandwidth**: The PLL's ability to track variations in the input frequency.
