[QUOTE="Femme_physics, post: 4307360, member: 272837"] [h2]Homework Statement [/h2] A load cell converts weight to voltage. It's known that the transmission of a certain measurement system is 5 mV/kgf In a computerized control system, it is necessary to translate the analog signal, which the transducer sends off, to a digital signal through an A/D converter. In a certain weight system, it is necessarily to measure weight in the range of 0-200 kgf, whereas the needed accuracy of the measurement is 0.5 kgf The A/D converter which is in the conversion system, is supplied by a 5V DC (Direct Current) voltage. 1) Pick the appropriate A/D converter for this measurement system (what's the required "data bits"?) [h2]The Attempt at a Solution[/h2] What bothers me is that I got n = 10 and he got n = 11. What gives? My solution: [URL=http://imageshack.us/photo/my-images/827/myann.jpg/][PLAIN]http://img827.imageshack.us/img827/7513/myann.jpg[/PLAIN] [/URL] My teacher solution: (Don't mind the Hebrew words) [URL=http://imageshack.us/photo/my-images/703/teacherans.jpg/][PLAIN]http://img703.imageshack.us/img703/5646/teacherans.jpg[/PLAIN] [/URL] [/QUOTE]
