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

when we view video on a computer the analog video is digitized and stored in the frame buffer of the video frame grabber card.suppose that a vedio is digitized at integer frame rate size 640*480 pixel and bit depth of 24 bit explain why you dont see a flicker effect on your workstation screen when display this video at NTSC frame rate ?
Justify the following statement: Signal distortion mechanism in optical fiberlimits the information rate of the signal?
Question 2: A system with 32768 possible colors is used to transmit ? × ? pixel image. What is the color depth of this system? How much storage is required for one image? What is the system bit rate if one image takes 1.3169 sec for transmission?
We have 14 sources, each creating 500 characters per second. Since only some of these sources are active at any moment, we use statistical TDM to combine these sources using character interleaving. Each frame carries 6 slots at a time, but we need to add four-bit addresses to each slot. Answer the following questions:(1)What is the size of an output frame in bits?(2)What is the output frame rate?(3)What is the duration of an output frame?(4)What is the output data rate?
What is the difference of the output stream when use statistical TDM multiplexer and synchronous TDM? Each frame consists of 3 slots. The bits arrive at the multiplexer as shown by the arrows. Note: If a cell is empty use the symbol: e
