A.2 Output with Data Select HIGH:
A.3 Photograph of your final Multisim circuit and submit it here below:
B. Design Project (Quartus II)
B1.Photograph of your final circuit and submit it here below:
- Why are the 330 Ω resistors required for the discrete logic circuit, but not for the MultiSim simulated circuit or the eSOC III circuit
- Create a partial truth table showing the requirements for a seven-segment decoder to output a hexadecimal digit. This requires four input bits and six output states, A – F. For each output state, show the segments a-g. The output states for the inputs 0 – 9 are the same as for the 74LS47 (see focus.ti.com). Use capital letters A, C, E, F and lower case for b and d.
- Why is the seven-segment display driven with an active-LOW signal using discrete logic and an active-HIGH with the eSOC board
