UTP kablo ile iletilen 5w lk sinyalin 10km mesafedeki alcdaki gc 10 mw olarak lulmse; a. En fazla 3dB lik sinyal zayflamasnda veri hatasz olarak okunabiliyorsa en az ka adet repeater kullanmak gerekir? Niin? Gsteriniz. b. Repeater mesafesinin daha uzun mesafede olmas nasl salanabilir? QUESTION .2. 011010000001110011 The above data will be transmitted by using digital signal. The encoding technique used has following features. - Having differential encoding - Having no synchronization - Having DC component a. Draw encoded signal of this data. (Assume that the last received signal element was in low signal level) b. If the modulation rate of this technique is 40KBaud, how much time is required to transmit the 2 MByte sized file? c. When the above data transmitted by using Bipolar-AMI and HDB3 encoding; Receiver recognized the error occurred in 5 th bit from the right-hand side after checking 2 nd bit from the right-hand side. How did it detect this error? Display with drawing the signal and explain it. Can it be corrected? Why? QUESTION .3. The following data will be transmitted. 110010010101 a. error control bits for the above data is calculated by CRC algorithm using G(x)=x2+ x polynom. After adding these bits to the data, it is sent. If the bits surrounded by rectangular are changed during transmission, what will be result of the receiver error control process. Prove it. b. This data is encoded with Hamming (7,4) and then sent. If the bits surrounded by rectangular are changed during transmission, is it possible to correct them? Why? Prove itStep by Step Solution
