Apply 5B: Use a 7-Segment Decoder to Drive a 7-Segment Display 1. Draw the wiring diagram of the 74LS47 device driving the common-anode 7-segment display through 3300 resistors in series, one per segment. 2. Build the circuit based on the wiring diagram. Tie off any control inputs of the 74LS47 device to enable it as a 7-segment decoder. Test all the segments of the display by temporarily connecting LT (pin 3 of 74LS47) to GND. Then connect D, C, B, and A of the 74LS47 device to power or ground rail and cycle through the 16 combinations to verify that the display shows the characters according to the truth table of the 74LS47 device. 3. Now interface the circuit in Apply 5A.4 with the circuit in Apply 5A.2 such that the display only shows the numbers controlled by N3N₂N₁No that are prime. When the numbers are non-prime, the display should be blank. Hint: use a single device with basic gates.

Transcribed Image Text:Apply 5B: Use a 7-Segment Decoder to Drive a 7-Segment Display
1. Draw the wiring diagram of the 74LS47 device driving the common-anode 7-segment display through 3300 resistors in series, one per segment.
2. Build the circuit based on the wiring diagram. Tie off any control inputs of the 74LS47 device to enable it as a 7-segment decoder. Test all the segments of the display by temporarily connecting LT (pin 3 of
74LS47) to GND. Then connect D, C, B, and A of the 74LS47 device to power or ground rail and cycle through the 16 combinations to verify that the display shows the characters according to the truth table of
the 74LS47 device.
3. Now interface the circuit in Apply 5A.4 with the circuit in Apply 5A.2 such that the display only shows the numbers controlled by N3N₂N₁No that are prime. When the numbers are non-prime, the display should
be blank. Hint: use a single device with basic gates.
Expert Solution
Step 1: Part 1:
Communicate with Apply 5A.4 Circuit:
Utilize a solitary gadget with fundamental entryways to connect the circuits.
Associate N3, N2, N1, and N0 to the contributions of the gate(s).
In view of the rationale for indivisible numbers, decide the condition for the presentation to be empowered or impaired.
At the point when the numbers are prime, permit the sign to go through and show the number.
At the point when the numbers are non-prime, block the sign to keep the showcase clear.
