How is mhz measured ie: 10 15 20 and when does it become ghz and in what unit is that measured?

Question

Can anyone give me a grid on this please?

Answer 1

Hi Pooh Bear

"Hertz" (hz) is a measure of frequency. 1 hertz is equal to one cycle per second (eg one full vibration per second, one full revolution per second, etc).

In Mhz (megahertz) the "mega" is the standard SI prefix meaning "one million". So 1 Mhz is 1 million hertz = 1 million cycles per second.

SI prefixes greater than 1 go like this:
* deka = 10
* hecto = 100
* kilo = 1000
* mega = 1000 000
* giga = 1000 000 000
* tera = 1000 000 000 000
* peta = 1000 000 000 000 000
etc

From this table, 1 gigahertz (Ghz) = 1000 000 000 hz = 1000Mhz.


Hope this helps!

Answer 2

Responders have correctly discussed the units involved, so I'll contribute a few words about the technology.
Frequency is measured by a gated electronic counter. The gate is opened for a precise amount of time (say, one second), and the individual oscillations of the source are counted until the gate is again closed. The count is displayed on a digital readout. Depending on the frequency to be measured, instruments to do this cost from a few hundred dollars to many thousands.

Answer 3

Plug a ic (intergrated circuit) chip up to a cathoid ray osilascope and measure the frequency. Set the range until you can see a wave. The most basic is a sign wave but more often used are square and sawtooth (triangle waves).
You can work out the frequency by 1 over time, or rather how many waves pass per second.
For example, these chips work on two voltages such as 5v and 2.3v for a cmos chip and we know them as binary one's and zero's.

Answer 4

Mhz is a metric unit of measure and so it goes in units or ten so 1000 hz is a khz and 1000000hz or 1000 khz is equlivent to 1mhz and 1000000000hz or 1000 Mhz is a Ghz. and so on The units are kilo mega giga and even goes higher to tera pico and so on.

Answer 5

well the frequency is pretty well handled..lets talk about the actual measurement of the field itself.

the instrumentation i measured radio-frequency fields with turned the frequency into heat by thermocouples, and the minute heat changes became the measurement.

the only people in the world that made a measurement device was the NARDA corporation: and yes, there equipment was sky high.

Answer 6

Ghz is measured in Ghz.... e.g. 10Ghz = 10,000,000,000Hz.

1 Hz = 1 cycle per second. Imagine a sine wave with a period of exactly 1 second. A 10Mhz signal will have 10,000,000 waves in 1 second, i.e. 10,000,000 'peaks' in that time span.

Answer 7

1 mhz = 100 hz
1000 mhz = 1 ghz
I believe :)

Answer 8

One hertz (Hz) is one cycle per second, so 1MHz (Megahertz) is a million cycles per second, 1GHz (Gigahertz) is a thousand million cycles per second and so on.

Answer 9

nemasisofbull

tell me more r answer is perfect for a question i was plannign to ask
im voting u best answer for sure.

Answer 10

1000mhz = 1ghz
