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.
When the neutral switch is open where do the line current flow to?
There is never a switch installed in a neutral line.
What happens to the power in the carrier after frequency modulation?
In FM the carrier is still present and the power is still there, at a constant amplitude at the transmitter. It's only the frequency of the carrier that alters, in time with the audio applied to it. The louder the sound the further the frequency shifts.
What the difference between single side band single carrier transmission and full carrier AM?
1. Single-sideband transmission requires only half as much bandwidth as double sideband.2. SSBSC require less total transmitted power than full carrier AMIn full carrier AM, the transmitted signal consists of two sidebands (containing the transmitted information) and the carrier signal. Long ago, it was realized that both sidebands contained the same information, and the carrier signal could be supplied by the receiver. Thus, if you suppress transmitting the carrier and one sideband, you can use the available power to increase the power in the remaining sideband.
Where would power factor capacitors be installed on a 3 phase motor?
Power factor capacitors can be installed on a three phase motor between the motor contactor and the overload heater block.
What is power line carrier communication?

What is power line carrier comunications?
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 = Carrier Power * 5
You have a 91 Buick LeSabre that has struts you have a carrier for a power wheelchair mounted on the back How can you raise the back of the car up some more?
have air-shocks installed
Can a sim card from a Samsung VGA 1000 flip cell be installed in a Sanyo flip cell SCP 7300 same carrier?
yeah if its from the same carrier
Why would 2005 dodge ram new fuel pump be blowing fuel out around top?
Broken/miss-installed line.Broken/miss-installed line.
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.
What are difference between bus reactor and line reactor?
A bus reactors a devise installed in a bus to maintain system voltage when the load on the bus changes by releasing reactive power as usable power to bolster the voltage. A line reactor is placed in line at point of use or just after a transformer to maintain a stable amperage to the user, capacitor.
What can not be installed from the command line by the ServerManagerCmd.exe utility?
Applications
What is the average cost for 220 line to be installed?
$1,000.00
What if your company has decided to order adsl from its local telecommumications carrier you call the carrier and find out that your office is located 17000 feet from the nearest co given adsl potenti?
Depends. You need to find out if your local carrier supports ADSL 2+ or not. 2+ DSL can go up to 30000 feet. The speed is dependent upon the quality of the line, but i have installed many 3.0 mbs DSL lines at 17k feet. You should have no problem getting 3.0 mbs service if the carrier has the ADSL 2+ technology in place.
