1)
An ANPR system takes two images of each passing car - one on the car's approach and one as it departs. Each image is 700 pixels wide and 225 pixels high. Each pixel is stored using one byte. On average, three cars pass per minute. If each uncompressed image is sent back to the control centre for processing, which option is closest to the average rate of data transfer?
A ) 63 kilobit per second
B ) 246 bits per second
C ) 340.48 kilobit per second
D ) 126 kilobit per second
E ) 90.75 Megabytes per second
F ) 120.46 kilobit per second

2)
2)In a proposed telesurgery application the images will be transmitted at 2x108 (the 8 is above the 10)m/s over a round-trip distance of 500 km. The compression and decompression processes for the images will take a total of 23 ms. What is the largest permissible value for the other sources of delay if the total round-trip delay is to be at most 35 ms?
A)3.5 ms
B)13.5 ms
C ) 9.5 ms
D ) 6.75 ms
E ) 23.5 ms
F ) 17.2 ms
