Chapter 10 Multiplexing and Demultiplexing

Example 10.1 Page no 368

#Given
BW_service = 860*10**6
BW_ch = 6.0*10**6

#calculation
total_ch = BW_service/BW_ch

#result
print"Total number of channels are ",round(total_ch,0)

Total number of channels are  143.0

Example 10.2 Page no 380

#Given
channels =16
sampling_rate= 3.5*10**3
w_len=6

#Calculation
available_ch =channels-1
bpf =channels*w_len
data_rate = sampling_rate * bpf

#Result
print"(a) Available channels are ",available_ch
print"(b) Bits Per Frame = ",bpf
print"(c) The serial data rate ",data_rate/10**3,"Khz"
 

(a) Available channels are  15
(b) Bits Per Frame =  96
(c) The serial data rate  336.0 Khz
