2. The VGA specifications give the following details for the parts of a single horizontal scan: Active Data 25.422 μs (colors!) Front Porch 0.636 μs (dark time) Sync Pulse 3.813 μs (dark time) Back Porch 1.907 μs (dark time) A. Calculate the total time for a complete horizontal scan line (sum all the parts above). Calculate the horizontal scan rate (how many scan lines per second?) expressed in kilohertz (kHz). B. Calculate the number of clock cycles for each of these parts of the signal, including the total (divide the time by the time per clock cycle, calculated in step 1). As a reality check, the data should be 640 pixels wide (remember, 1 clock cycle = 1 pixel) and the whole scan line should be 800 pixels. Round your answers to integers since we can only count in units of whole pixels. (2) 3. IBM specified that 480 of these scan lines are used to make a complete picture. Calculate the total time for these 480 scan lines (the vertical active data). Express the answer in milliseconds (ms)

2. The VGA specifications give the following details for the parts of a single horizontal scan:
Active Data 25.422 μs (colors!)
Front Porch 0.636 μs (dark time)
Sync Pulse 3.813 μs (dark time)
Back Porch 1.907 μs (dark time)
A. Calculate the total time for a complete horizontal scan line (sum all the parts above). Calculate
the horizontal scan rate (how many scan lines per second?) expressed in kilohertz (kHz).
B. Calculate the number of clock cycles for each of these parts of the signal, including the total
(divide the time by the time per clock cycle, calculated in step 1). As a reality check, the data
should be 640 pixels wide (remember, 1 clock cycle = 1 pixel) and the whole scan line should be
800 pixels. Round your answers to integers since we can only count in units of whole pixels.
(2) 3. IBM specified that 480 of these scan lines are used to make a complete picture. Calculate the
total time for these 480 scan lines (the vertical active data). Express the answer in milliseconds (ms)
