Review questions: the graph below is the applied voltage (x-axis) and resulting current (y axis). Place the labels from this list onto the graph: reverse bias region, forward bias region, and turn- on voltage. 10 Vp Discussion: Introduction to logic gates Procedure for the group: Refer to 'Introduction to TTL Logic Gates?t This lab will use a 7404 chip (inverter) 1. Construct the circuit in Figure below on your breadboard. VCC VCC 5.0V 5.0V S1 Pin 14 Pin 1 Pin 2 Pin7 R1 3300 LED1 ị 7404N
2. A switch is used to test the operation of the gate. Using the LED as an indicator, fill in the table below. Using the multimeter, measure the value of the voltage at the output of the logic gate for each condition. Remember: a 'O' is zero voltage, *1' is +5 voltsé ܒܐ Pin 2 Voltage le oe le ܒܢ tt 3.
