Part 1- Binary-to-Decimal Number Conversion Theory: 1. Enter the decimal, hexadecimal, and BCD numbers for each of the following binary numbers. Binary Hexadecimal BCD Decimal 0000 0 0000 0 0001 1 0001 1 0010 2 0010 2 0011 3 0011 3 0100 4 0100 4 0101 5 0101 5 0110 6 0110 6 0111 7 0111 7 1000 8 1000 8 1001 9 1001 9 1010 A Invalid 10 1011 B Invalid 11 1100 C Invalid 12 1101 D Invalid 13 1110 E Invalid 14 1111 F Invalid 15 2. Explain major differences between binary and BCD numeric representations. Ans 2: BCD each digit of a decimal number is coded as a 4 bit binary number between 0 and 9. This is not used too often as it is difficult to do calculations in BCD as opposed to binary, and it is not efficient – uses more bits than a binary coded number would. In Binary the number is converted to base 2, binary code. Planning: 1. Provide a list of places that you can obtain the datasheets for the following components: · SN74LS47 Binary to BCD Decoder http://www.onsemi.com/pub_link/Collateral/SN74LS47-D.PDF · MAN72 Seven Segment Display http://web.ece.ucdavis.edu/~bbaas/180a/Datasheets/man72a.pdf · 4116R 1-331 330 ohm Resistor Pack http://www.digchip.com/datasheets/parts/datasheet/1896/4116R-1-331-pdf.php Preparation: 2. Why is it important to follow ESD safety procedures when handling electronic components? What are some of the main considerations? Ans2 These precautions protect sensitive electronic components Extremely fast response time Low clamping and operating voltage Capacity of handle high peak ESD current Ability to remain undamaged by repetitive ESD strikes Minimize size Minimal reverse leakage current Wiring Procedure: 3. Complete the wiring diagram. Refer to Lab 1.1 Figure 1-4 and image 1 & 2 of the ET1220.U1.Lab.Images PowerPoint. Use MS Paint to complete the wiring diagram. Test Procedure: 4. Record the observed values from Lab 1.1 Table 1-1. Indicate which segments are illuminated for each input setting.
