MHz

[ɛm ɛtʃ z ]

Definition

^{Context #1 | Noun}

scientific measurement

MHz, or megahertz, is a unit of frequency equal to one million hertz. It is commonly used to measure the frequency of electromagnetic waves, including radio waves, and in digital electronics as the clock speed of microprocessors. This term is frequently used in contexts such as telecommunications and audio technology.

Synonyms

frequency unit, megahertz.

Examples of usage

The radio station broadcasts at a frequency of 101.5 MHz.
My laptop's processor runs at 2.5 GHz, which is equivalent to 2500 MHz.
The Wi-Fi router operates on both 2.4 GHz and 5 GHz bands, which are 2400 MHz and 5000 MHz, respectively.
Most FM radio stations operate in the range of 88 MHz to 108 MHz.
The performance of the device can be affected by its operating frequency, measured in MHz.

Interesting Facts

Etymology

The term 'Hertz' comes from Heinrich Hertz, a German physicist who proved the existence of electromagnetic waves.
The 'mega-' prefix means a million, so 1 MHz equals one million cycles per second.
The measurement was named officially in 1930, bringing a new standard to describe frequency.

Technology

MHz is commonly used to specify the operating speed of computer processors, with higher numbers indicating faster processing.
In radio communications, MHz indicates the frequency used to transmit signals. For example, FM radio typically operates between 88 to 108 MHz.
Wireless networks use MHz frequency to manage bandwidth, affecting internet speed and range depending on the MHz assigned.

Science

Electromagnetic waves, including light and radio waves, are measured in hertz, illustrating the wide range of frequencies in the universe.
A higher MHz value can correspond to higher energy states in systems, impacting how we understand and harness these energies.
The speed of light in vacuum can be calculated with frequency (in MHz) and wavelength, showing the relationship between these concepts.

Popular Culture

Many video game consoles boast their processing speed in MHz, often in marketing to showcase power compared to competitors.
The term has appeared in various sci-fi media, emphasizing advanced technology with higher MHz resulting in superior capabilities.
In the realm of music production, sound equipment specifications often list MHz for sampling rates, affecting the clarity of recordings.

History

The adoption of MHz in technology has evolved from analog to digital, impacting how we experience communication today.
In the late 20th century, mobile phones began using MHz frequencies, opening the door to modern wireless communication.
The first commercial FM radio stations began broadcasting in nearly the MHz range we use today, changing how music and news reached the public.
