Unformatted text preview: 6. A sine wave has a frequency of 5 KHz. What is the period? T = 1/5KHz = 0.2 msec 7. Encode the data stream 00111010 using Manchester line coding. Show the beginning and end of each bit time. Please be neat. Solution is to hard to create in word. See me. Sorry. 8. What is the maximum capacity (in bits per second) of a perfect channel which accepts frequencies between 1000Hz and 3000Hz and transmits a signal with four signal levels? capacity = 2 * BW * log 2 L = 2 * 2000 * 2 = 8000 bps 9. Assume that a channel accepts frequencies between 0 Hz and 4000 Hz and has a signal to noise ration measured at 7 (not in dB). What is the maximum information rate of the channel (in bits per second)? capacity = BW * log 2 (1 + SNR) = 4000 * log 2 (8) = 4000 * 3 = 12000 bps...
