KHz is a unit of frequency equal to 1,000 cycles per second. It is commonly used to measure frequencies in various fields, including technology, computing, programming, and communications. How does kilohertz relate to sound? In the context of sound, kilohertz represents the frequency of audio ...
Radio frequency (RF) is a measurement representing the oscillation rate of electromagnetic radiation spectrum, or electromagnetic radio waves, from frequencies ranging from 300 gigahertz (GHz) to as low as 9 kilohertz (kHz). With the use of antennas and transmitters, an RF field can be used for...
Frequency is typically used to describe electrical equipment operation. Below are some common frequency ranges: Power line frequency (normally 50 Hz or 60 Hz). Variable-frequency drives, which normally use a 1-20 kilohertz (kHz) carrier frequency. Audio frequency range: 15 Hz to 20 kHz (the ...
The role of each component of the radio frequency front-end is not complicated. For example, the amplifier is to amplify the signal to make the signal farther; the filter is to remove the clutter and make the signal more "pure"; the antenna switch is used to control the enabling and clo...
2. With a computer processor or CPU, GHz is a clock frequency, also known as a clock rate or clock speed, representing a cycle of time. An oscillator circuit supplies a small amount of electricity to a crystal each second measured in kHz, MHz, or GHz. "Hz" is an abbreviation of Hert...

You’ll often see audio specifications quote a range of frequencies, such as 20Hz-20 kHz, followed by the variation in the frequency response quoted in decibels, such as +/- 6 dB. This simply tells us the maximum deviation at any point between the given frequencies, so it doesn’t tell...

任何无线通信系统都会被划分到专属的频段,这个频段就是占据一定频率范围的频谱。广义的来讲,国际上是把频率范围在3 kHz到300 GHz的频谱就称射频。 Imagine a world without RF, or Radio Frequency technology. This would mean not only losing your handheld devices, but also the ability to forecast weather,...
Manipulating the frequency spectrum is one of the most important skills in recording and mixing. We explain the different types of EQ you can use in your mix and share some tips on how to get the best from them.
