Q1:

A video transmission system transmits 625 picture frames per second. Each frame consist of a 400 x 400 pixel grid with 64 intensity levels per pixel. The data rate of the system is

A 16 Mbps

B 100 Mbps

C 600 Mbps

D 6.4 Gbps

ANS:C - 600 Mbps

Data rate = n*(No of frames*Pixel grid).

2^n = 64.

2^n = 2^6.

So n = 6.

Data rate = 6*625*400*400.

= 600 mbps.
