Consider the following signal encoding technique. Binary data are presented as input, am for m= 1,2,3,...Two levels of processing occur. First, a new set of binary numbers are produced: Bo=0 bm = (am + bm-1)mod 2 These are then encoded as Cm = bm - bm-1 On reception, the original data are recovered by: %3D am = Cm mod 2 a. Verify that the received values of equal the transmitted values of am. b. What sort of encoding is this?

Consider the following signal encoding technique. Binary data are presented as input, for m = 1, 2, 3, ... Two levels of processing occur. First, a new set of binary numbers are produced: B. = 0 bm = bm (am + bm-1)mod 2 These are then encoded as cm = bm - bm-1 On reception, the original data are recovered by: am = cm mod 2 a. Verily that the received values of equal the transmitted values of am b. What sort of encoding is this? Note: view attached image for better understanding of question
Consider the following signal encoding technique. Binary data are presented as input, am
for m= 1,2,3,...Two levels of processing occur. First, a new set of binary numbers are
produced:
Bo=0
bm = (am + bm-1)mod 2
These are then encoded as
Cm = bm - bm-1
On reception, the original data are recovered by:
am = Cm mod 2
a. Verify that the received values of equal the transmitted values of am.
b. What sort of encoding is this?
