almost 8. How does concurrence apply to the communications industry? Ans= In form of media press and public speaking.

being unfaithful. What is the decibel decrease of a signal that starts at point A having a strength of 2000 w and ends at level B having a strength of 400 w? Ans= 10*log10 (400/2000)

15. What is the decibel loss in a signal starting at 60 watts and experiences a 10-dB damage over a offered section of cable? Ans= 10-db = 10*log10(x/50)

11. Precisely what is the decibel loss of a sign that loses half the power during transmission? Physical exercises for the Details sections:

Ans=

doze. Using Nyquist's theorem, determine the data transfer rate of your signal that has 16 several levels and a rate of recurrence of 20, 000 Hz. Ans=

13. Employing Shannon's theorem, calculate the information transfer level given this information: transmission frequency = 10, 000 Hz, sign power sama dengan 5000 w and noise power sama dengan 230 w Ans=

16. Using Nyquist's theorem and given a frequency of 5000 Hertz and a data rate of 20, 000 bps, just how many signal levels (L) will be needed to convey this kind of data Ans=

12-15. Draw in chart form the ac electricity representation with the bit style 11010010 for the digital encoding plans NRZ-L, NRZI, Manchester, gear Manchester, and bipolar- AMI. Ans=

16. Precisely what is the bit par seconde rate of a digital transmission that utilizes differential Stansted and contains a data transfer level of 2k bps? Ans= 2000bps 5. 2 = 4000bps (In differential Stansted it uses a couple of as a signal) 17. Why is the cable inside turned pair turned? 2 . How does crosstalk take place in twisted match wire? Ans= Very often is made up of one or more pairs of wire connections and they are turned around one another. Electromagnetic light is released from one line which is acquired by the second wire. 18.
