Homework Answers
(a)
dot frequency = 300 dots per inch
resolution = 8.5 * 11 inch = 935 inches
So,total number of dots = 300 * 935 = 280500 dots
1 dot = 1 bit
Memory occupied =
280500 dots = 280500 bits = 0.02805 MBits
(b)
If dot frequency increases = 1200 = 300 * 4 per inch
Therefore,
Memory occupied - 0.02805 * 4 = 0.11220 MBits

When dots are placed on a page from a laser printer, they must be close enough so that you do not see the individual dots of ink. To do this, the separation of the dots must be less than Raleigh's criterion. Take the pupil of the eye to be 3.3 mm and the distance from the paper to the eye of 40 cm; find the maximum separation (in cm) of two dots such that they cannot be resolved. (Assume the...

In lectures we discussed how bitmap images are stored as a grid of pixel values. Each pixel has a colour value, and colour can be encoded using the RGB encoding scheme. In lectures we also discussed using the RLE compression technique. Examples of the RLE technique being used to compress text were given. Instead of storing every single character individually, if there is a sequential run of identical characters, data on one character is stored along with a count of...

Start-up costs: 1) The Boulevard Mall charges you $2,500 rent per month, which includes utilities, telephone, cleaning, and maintenance. You estimated that 90% of the rent was related to factory operations and 10% was related to selling and administrative activities. 2) You order white, cotton t-shirts from a T-shirt wholesaler. Each T-shirt costs (including taxes, shipping, and handling) $3.75 to purchase. 3) To store T-shirts that were bought, but not yet imprinted, you rent a storage unit. The storage unit...
