University of Wollongong School of Electrical, Computer and Telecommunications Engineering ECTE290 2 Q4 Using only NAND gates and assuming that all inputs and outputs are asserted high, draw the logic circuit for the SOP expression found in question 1 2 3 for G, OUT1, AND OUT2 Q5 A seat belt system has pressure sensors in the driver and front passengers seat. The seat belts also have sensors to indicate that they have been connected. i. Draw a truth table which has a output F which is a logic 1 when the driver is seated and

Unformatted text preview: has the seat belt on. For another output Y which is logic 1 when either the driver or the front passenger are present and one or both have not got their seat belt on ii. Use two 4 variable K maps to minimize the logic expressions for F and Y in SOP form. iii. Using only NAND gates and given that all inputs and outputs are asserted high draw circuit diagrams which will implement the minimized SOP logic Q6 A 220/110V, 10kVA transformer has a primary winding resistance of 2.5 Ω and a secondary winding resistance of 0.06 Ω. Determine i. The turns-ratio of the transformer ii. The primary current at rated load iii. The secondary current at rated load iv. The total resistance referred to the primary side v. The total resistance referred to the secondary side...
