DE FINAL EXAM REVIEW 1. Express each of the following numbers using the appropriate SI prefix. Don’t forget to retain the units. a. 0.000047 F = b. 17500000 Hz = c. 0.0000000157 A = d. 6800000 = e. 0.00425 V = 2. Convert the following numbers into the SI prefix shown. a. 6800 pF = b. 2.7 M = c. 4.24 GHz = d. 25.67 F = e. 0.0127 nSec = (Red / Violet / Brown / Gold) f. Rc = (Brown / Red / Green / Gold) g. Rd = Resistor Re (Blue / Gray / Orange / Gold) h. Re = i. 3. For each of the circuits shown below, calculate the value for RT. Be sure to put your answer in proper engineering notation and use the correct units. Calculations: a) Rt= a) c) Rt= c) 4.Using the laws of circuit theory, solve for RT, IT, IR1, IR2, IR3, & IR4. Be sure to put your answer in proper engineering notation and use the correct units. RT IT VR1 VR2 VR3 = = = = = VR4 = 5.For each of the two analog signals shown below, determine their amplitude (peak), amplitude (peak-peak), period (T), and frequency (F). Be sure to put your answer in proper engineering notation and use the correct units. Amp(peak): Amp (peak-peak): Period: Frequency: Amp(peak): Amp (peak-peak): Period: Frequency: Note: Why isn’t the above signal considered a digital signal? 6.As a digital designer, you will occasionally need to redesign an existing circuit. In doing so, you will come across part numbers that you are not familiar with. Use the Internet to identify the functionality and manufacturer of each of the part numbers listed below. Note that many parts will have several manufacturers. For the purpose of completing this table, list one. Also, do not print these datasheets. Simply view them online and extract the necessary information. Part Number DM74LS00 SN74LS02 DM74LS75 SN74LS86 MAN6760 IC Name / Function Manufacturer 7. When you design a digital logic circuit, you will often need a gate that performs a specific function. You may be unsure of its part number. Use the Internet to identify the 74LS series part number for each of the following five gates. Again, do not print these datasheets. Simply view them online and extract the necessary information. Gate Symbol Gate Name / Function Binary to Decimal a) 1100 (2) = (10) b) 11010 = (10) (2) c) 111001 (2) = (10) d) 1010011 (2) = (10) e) 10000101 (2) = (10) 74LS Series Part Number 8. Write the Logic Expression for the following 1. 2. M N F1 X Y F2 0 0 1 0 0 1 0 1 0 0 1 0 1 0 0 1 0 1 1 1 1 1 1 1 F1 = F2 =
