Power in USA is 60 hertz. Typical speech is between 0 and about 16,000 Hz. In power line carrier applications the 60 Hz is modulated by a higher frequency that is in turn modulated by a transducer that captures speech. With the proper modulator and demodulators you can either modulate the 60 Hx carrier to send a transmission or demodulate to receive.

Relation between total power and carrier power?
Total power is the summation of the carrier power and any additional sidebands or noise present in the signal. Therefore, the carrier power contributes to the total power but is not the sole component. The carrier power represents the power contained in the main signal frequency.
AM power content of the carrier is maximum when modulation index is?
The AM power content of the carrier is maximum when the modulation index is zero. At this point, there is no modulation applied to the carrier signal, meaning the entire power is concentrated in the carrier frequency itself. As the modulation index increases, the power is distributed between the carrier and the sidebands, resulting in a decrease in the carrier's power content. Thus, maximum carrier power occurs at zero modulation.

What the AM transmitted power equation?
Total Power = Power of unmodulated carrier + 2 * Power per sideband
How do you add a new phone onto your existin shared plan?
The process is carrier-specific. Call your carrier and ask to add a line.
Can you keep your land phone line number if you get a cell phone?
Yes you can. Your phone line has nothing too do with your cell phone. In fact, for most people your phone line carrier is completely different from your cell phone carrier. And you phone line has absoloute no connection TO YOU HOME PHONE AT all
What is a better air conditioner Goodman or Carrier?
That depends, a top of the line Goodman may be a better investment than a builders grade Carrier.
How do most users of frame relay connect to their carrier?
A leased line is the most common way that users connect to their carrier's point of presence
What is the frequency and wave form of old land line phone carrier?
First answer.The landline phone has no carrier frequency it is a baseband signal with a 3KHz bandwidth.Correction:So there is a signal that can handle a 3KHz bandwidth, what do you call that signal? I call it a carrier, if you don't have a carrier, you will need to amplify the audio every 30 meters else you will end up with no audio at the end of the line. So there is a carrier on all phone lines. Note the carrier signal are up to 90 VPP and is AM modulated at the instrument, but in digital systems the carrier are switched on and of, FSK modulation.
What is Carrier Power of a radio transmmiter?
Carrier power is the power that comes out of a transmitter and goes to the transmitting antenna at the moment when no information is being added to the transmission ... no music, voice, sound, picture, data, noise, hum, no nothing. Only what they call a "bare carrier". There are different methods of adding information to the carrier, called "modulation". Some of them change the instantaneous power of the transmitter, others don't. Examples: AM rapidly varies the transmitter power. Properly adjusted FM doesn't.
What is the definition for aircraft carrier in basketball?
A tall and/or large player. 'Aircraft carrier' is a slang term for a center or power forward.
