    • Step 5(listed as step 4) Replace the 74LS47 with a 74LS48 and modify the circuit so it will still work, screenshot it displaying the number 5.
  3. Hand in Completed Activity 2.3.1 Hex and octal paper
  • Create and analyze circuits with 7-segment displays and drivers in various combinations.
30 Which pins should be high to display a "4" on a common CATHODE 7-segment display?
  1. Due today: Create a 7-segment display page in your notebook:
    1. A diagram labeling the 7 segments on a 7 segment display
    2. From your notes on 7 segment displays; cut out the simple common anode and common cathode circuits in the middle of the page and add them to your notebook (there are scissors and glue sticks on the front table and extra copies of the handout)
    3. From your How 7-segment works notes;
      • Add the diagrams that show what the hex digits 0-F look like on a 7-segment display
      • Add your kmap and equation for the one segment you did an equation and circuit for.
      • A print out of your multisim circuit showing the DCD hex display with the one segment that you did the Kmap and circuit for.
  2. Due tomorrow: Completed Activity 2.3.1 Hex and octal paper
  • Document the 2 kinds of 7-segment displays and how logic circuits are used to display hexadecimal digits on them.

 

7 segments
29 Convert the hex number 2D to binary, decimal, and octal.
  1. Simulate the DCD hex circuit with 4 switches.
  2. Work through how a 7 segment display circuit works. Each group is assigned on segment from a-g to Kmap and build a circuit for.
  • Simulate a display circuit
  • Use the design process to explain the inner workings of a 7 segment display
       
26 Convert the binary number 100011001010 to hex and octal
  1. Complete hex and octal. Discuss conclusion questions.
  2. Learn about 7 segment displays with the powerpoint and fill in the notes.
  • Review conversions from binary to hex and octal.
  • Describe the features of 7 segment displays.
25 What is the largest binary number that can fit into 4 bits?
  1. Learn about hexadecimal and octal.
  2. Do worksheet on hex and octal
  • Convert numbers from decimal, binary, octal and hexadecimal
