Frequency Multiplier Conversion
Some TV devices want channel frequencies keyed in
Mhz, Khz or Hz.
Here is a quick conversion table to help you work out the values.
Abrev.=Multiplier (Tera, Giga, Mega, Kilo)
Thz = TeraHertz
Ghz = GigaHertz
Mhz = MegaHertz
Khz = KiloHertz
Hertz = base unit
e.g. 177.5Mhz = 177500Khz = 177500000Hz -
1Thz = 1,000Ghz =
1,000,000Mhz = 1,000,000,000Khz =
1,000,000,000,000hz
1Ghz = 1,000Mhz = 1,000,000Khz = 1,000,000,000Hz
1Mhz = 1,000Khz = 1,000,000Hz
1Khz = 1,000Hz
1Hz = 1cps (cycle per second and Hertz are the same thing)
All these numbers refer to the frequency of the TV signal's carrier
wave as the number of oscillations in 1 second. The TV program you want
is a series of signals super-imposed on the carrier wave or and encoded
series of carrier waves for DiGiTal TV.
Each carrier wave acts
something like a
house address, each house has a physical width as does TV channels, in
Australia that is 7Mhz PAL(B), 7Mhz to the next address and so on.
To follow through on this analogy the occupants you want to see are at
frequency X and in room Y at a specified time Z, in other words you
want Channel 12, ABC1 at 7pm for the NEWS service.
73's for now.
