Question

2. A digital data is transmitted at a rate of Rbit = 400 bits/sec. A sample of this data is observed the data source output as shown below 10110. Plot the data if the binary data is encoded uisng a. non-return to zero (NRZ) format. Label completely. b. M-ary signaling where M=4. Data Source Rbits = 400 bits/sec d(t): 101101

Answer 1

type of digital One O" M-ary signalling where M= 4 M-ary transmission is a modolation whore instead of transmitting bit at a time, two lor more bits are transmitted simultaneously. This type of trans – mision' results in Jeduced channel bandwidth = M = 4 where 4 combinations will be M= 4 when n=2 'M= 2? = 2 = 4 g? means Quadrature signalling" is not of bits O TO IR 3 - T .bit stream 10 - +3 +1 T= 2.5ms -1 To = 5m5
