Find the number what devices that could be accommodated by a T1-type TDM line if 1of the T1 line capacity is reserved for synchronization purposes 110-bps teleprinter terminals?

Hello Friend,
The answer essentially starts with realizing that a T1-type line is essentially the same as Digital Signal 1 Line (http://en.wikipedia.org/wiki/T1). The data rate for which is 1.544 Mbps.
So just convert this to bps: 1544000 bps.
I'm assuming "1" refers to 1%, so if 1% must be used for synch overhead, for actually transmitting data we can only use 99% of it or: 1528560.
Since TDM gives equal time slices to all of the the devices, just divide this rate by the bps need by each device (110 bps).
This division gives us = 1528560bps / 110bps = 13896 devices.
Enjoy!

What is the channel capacity for a teleprinter channel with a 300-hz bandwidth and a signal-to-noise ratio of 3dB?
I m not sure but it should be something like this Shannon capacity(channel capacity) C = B Log2(1+ s/n) C= channel capacity B = bandwidth S/N = signal to noise ratio in power units as the S/n is in db , first we have to convert it. 3db= 10^3/10 = 10^0.3= 1.9926 now putting in the formula C = 300log2(1+ 1.9926) C = 474.81 bps
How do you power a 1500 watt AC appliance in a car?
You can buy an "inverter." It plugs into the cigarette lighter or accessory plug or directly clips to the battery terminals and converts the 12 volt DC to AC. You can then plug your appliance into it. Be sure to get an inverter that is the right wattage capacity for your device.
