estion 4 (a) Expand the acronym CCD marks) (b) State how charge is 'read out' of a CCD detector and how this could result in a higher-quality digital image, as opposed to using a CMOS detector, when employed in a digital camera. (c) Determine the scale (to the nearest order of magnitude) at which engineering has to be carried out in order to generate a 7 megapixel image from a sensor measuring 2 cm x 2 cm. (d) Put the...

Digital Circuits CET 363 Traffic Control Problem Scenario: Intersection of an access road and main road with traffic signal. See figure. Vehicle-detection sensors are placed along lanes C and D (main road) and lanes A and B (access road). These sensor outputs are LOW (0) when no vehicle is present and HIGH (1) when a vehicle is present. The intersection traffic light is to be controlled according to the following 1. The east-west (E-W) traffic light will be green whenever...
