kilohertsiga

Kilohertz, often abbreviated as kHz, is a unit of frequency equal to one thousand hertz. It is commonly used in the fields of electronics, telecommunications, and audio engineering to measure the frequency of signals. One kilohertz is equivalent to 1,000 cycles per second. This unit is particularly useful for describing the range of human hearing, which typically spans from 20 Hz to 20 kHz. In digital signal processing, kilohertz is also used to specify the sampling rate of audio signals, with common rates including 44.1 kHz for compact discs and 48 kHz for digital audio workstations. The kilohertz scale is also employed in radio communications to denote the frequency bands used by various services, such as AM radio (535-1705 kHz) and FM radio (87.5-108 MHz). Understanding kilohertz is essential for comprehending the principles of sound, signal processing, and wireless communication technologies.
