3. Compute the Euclidean Distance (D_{1}), City-block Distance (D_{2}) and Chessboard distance (D_{3}) for

points p and g, where p and q be (1, 2, 3) and (1, 5, 7) respectively. Give answer in the form (D_{1},

D_{2}, D_{3}).

a) (5, 3, 4)

b) (5, 4, 3)

c) (7, 5, 4)

d) (8. 7.4)

Answer :-

4. What is the minimum bandwidth required to transmit a grayscale image scanned at 100 PPI of size

3 inches x 4 inches, with a data compression ratio of 8:1, over a communication channel in 0.5

seconds, given that each pixel is digitized using 8 bits?

Hint: Data compression ratio is defined as the ratio between the uncompressed size and compressed

size: Thus, a representation that compresses a file’s storage size from 10 MB to 2 MB has a

compression ratio of 10/2 = 5/1

a) 3.84 Gbps

b) 1.92 Gbps

c) 1.48 Gbps

d) 5.12 Gbps

Answer :-
