Frequency measures how often an event repeats in a given time, typically in cycles per second, or Hertz. In electrical engineering, frequency determines the operation of alternating currents, radio waves, and audio signals. Whether it's measured in kilohertz for radio or megahertz for computing, understanding frequency is essential for optimizing signal transmission and ensuring efficient use of bandwidth in communication technologies.
- Hertz: The base unit of frequency, representing cycles per second, commonly used in audio and electrical engineering.
- Kilohertz: Equal to 1000 Hertz, often used for radio frequencies.
- Megahertz: Equal to 1 million Hertz, commonly used in broadcasting and computer processing speeds.
- Gigahertz: Equal to 1 billion Hertz, typically used for higher frequency applications like modern wireless communication and computer processors.
- Terahertz: Equal to 1 trillion Hertz, used in advanced technologies like spectroscopy and medical imaging.
- Revolutions-per-minute (RPM): A unit used to measure the frequency of rotation, commonly used in motors and machinery.
- Cycles-per-second: Another term for Hertz, used to describe the frequency of oscillations or waves.
- Decahertz: Equal to 10 Hertz, used for specific scientific or technical measurements.
- Centihertz: Equal to 0.01 Hertz, used for ultra-low frequency measurements.
- Millihertz: Equal to 0.001 Hertz, used for very slow oscillations.
