What is a kilohertz (KHz)? 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?
What is Frequency Used to Measure? 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 frequenc...
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...

1. What is the clock frequency that ARM instructions are executed? 2. If I toggle one of the GPIO pin by accessing its address directly, what is the possible square wave frequency that I can get? ALT_CLK_IN_PIN_OSC1 = 25 MHZ
Frequency is the number of cycles in a given unit of time. The “cycles” can be movements of anything with periodic motion, like a spring, a pendulum, something spinning, or a wave. The frequency formula is used to calculate a wave’s frequency. For example, the sound of the fan is...
Radio frequency (RF) refers to the rate of oscillation of electromagnetic radio waves in the range of 3 kHz to 300 GHz, as well as the alternating currents carrying the radio signals. This is the frequency band that is used for communications transmission and broadcasting. Although RF really ...
What's the Frequency Kenneth? by R.E.M.And now back to the subject at hand...Some of the information below came from Philips (now NXP, or is in Ampleon?), from their downloadable "RF Manual", which we highly recommend that you check out. In 2015, Hossein helped us track down ...
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...
