Frequency stability refers to the ability of a system, such as an electronic oscillator or a power grid, to maintain a constant frequency over time. This is crucial in applications like telecommunications and broadcasting, where consistent signal quality is necessary for clear communication. Variations in frequency can lead to distortion or loss of information. In power systems, frequency stability ensures that the electricity supply remains reliable and balanced. If the frequency fluctuates too much, it can cause equipment to malfunction or even lead to blackouts. Maintaining frequency stability is essential for the efficient operation of both electrical grids and various electronic devices.
