what are mhz used to measure?
149503
(MegaHertZ) One million cycles per second. MHz is used to measure the transmission speed of electronic devices, including channels, buses and the computer's internal clock. A one-megahertz clock (1 MHz) means some number of bits (1, 4, 8, 16, 32 or 64) can be manipulated at least one million times per second.

For any device that uses a standard speaker driver, the Hz-KHz value is the range of audible sound vibrations that the speaker can produce. ... Hertz are units used to measure frequency. One hertz is defined as one cycle per second. So, a frequency measured at 20 Hz is traveling at 20 cycles (or waves) per second.

The frequencies of radar sets today range from about 5 megahertz to about 130 gigahertz (130,000,000,000 oscillations per second!). However, certain frequencies are also preferred for certain radar applications. Very long-range radar systems usually operate at lower frequencies below and including the D-band.

Since one hertz is one cycle per second, one kilohertz is equal to 1,000 cycles per second. Kilohertz is commonly used to measure the frequencies of sound waves, since the audible spectrum of sound frequencies is between 20 Hz and 20 kHz. For example, middle C (C4) on a piano keyboard produces a frequency of 261.63 Hz.

The most common measure of CPU speed is the clock speed, which is measured in MHz or GHz. One GHz equals 1,000 MHz, so a speed of 2.4 GHz could also be expressed as 2,400 MHz. The higher the clock speed, the more operations the CPU can execute per second.

In general, for services below 65 MHz, measurements of both the electric (E) fields and the magnetic (H) fields may be required. ... As a result, measurement locations are usually situated in the far-field region, and in general, only electric (E) field measurements are required.

The frequency (f) of an oscillation is measure in hertz (Hz) it is the number of oscillations per second. The time for one oscillation is called the period (T) it is measured in seconds.
552357
Any electromagnetic wave can be used in radar. The most commonly used radar waves have wavelengths between about 1 centimeter (30 GHz) to about 1 meter (300 MHz), but there are some radars using much larger wavelengths (up to about 50 meters) and much smaller wavelengths (well under a millimeter).

A frequency meter is an instrument that displays the frequency of a periodic electrical signal. Various types of frequency meters are used.

VHF is, by definition, the range of frequencies from 30 - 300 million cycles per second (megahertz or MHz). AM sends information my Amplitude Modulating the carrier frequency; FM on the other hand Frequency Modulates the carrier. Most VHF transmissions utilize FM as it has certain advantages in many applications.

10 MHz Reference. ... The 10 MHz frequency reference is used to phase lock the local oscillator in the LNB or BUC and thus make the local oscillator frerquency very stable. LNB: If you are trying to receive small carriers or making measurements then high frequency accuracy in your LNB helps.

Frequency is the rate at which current changes direction per second. It is measured in hertz (Hz), an international unit of measure where 1 hertz is equal to 1 cycle per second.
722231
Kilohertz - kHz is defined as thousands of cycles per second. Megahertz - MHz is defined as millions of cycles per second - 1000 x more than kilo.

In communications engineering, bandwidth is the measure of the width of a range of frequencies, measured in Hertz. Rate is the number of transmitted bits per time unit, usually seconds, so it's measured in bit/second. Equivalently, it can be given in symbols/time unit. The rate is proportional to the system bandwidth.

RAM speed is generally measured in megahertz, usually abbreviated as “Mhz.” This is a measure of the clock speed (how many times per second the RAM can access its memory) and is the same way CPU speed is measured. The “stock” speed for DDR4 (the newest memory type) is usually 2133 Mhz or 2400 Mhz.
945044
wave speed (v) is measured in metres per second (m/s) frequency (f) is measured in Hertz (Hz)
350546
Frequency and time period. f is the number of waves produced by a source per second, it is measured in hertz (Hz). T is the time it takes for one complete oscillation , it is measured in seconds.
