Kõrgefrekventselt

Kõrgefrekventselt is an Estonian adverb that translates to "at high frequency" or "with high frequency" in English. It describes a phenomenon or action that occurs at a rapid rate or involves oscillations with a high number of cycles per unit of time. The term is often used in scientific and technical contexts, particularly in physics, electronics, and telecommunications.

In physics, high frequency can refer to electromagnetic waves such as radio waves or light, where the oscillations of the electric and magnetic fields are very rapid. In electronics, high-frequency circuits are designed to operate with signals that change direction billions of times per second. This is crucial for applications like wireless communication, where information is encoded onto high-frequency carrier waves.

The concept of "high frequency" is relative and depends on the specific field of study. For example, what is considered high frequency in audio engineering might be low frequency in radio engineering. Generally, frequencies above the human hearing range (approximately 20 kHz) are often termed high frequencies. The precise cutoff can vary based on the application. Understanding and manipulating high-frequency phenomena are fundamental to many modern technologies.
