Study the circuit in Figure 1.30, and answer the following questions: a. What logic gate type does the indicator represent? b. What is the status (ON/OFF) of the indicator if push buttons A and B are pressed and released one time? c. What is the status of the indicator if push buttons A and B are pressed and maintained closed all the time? What is the status of the indicator if push button A or B is pressed one time? Show how you can modify the circuit to maintain the indicator status ON if push button A or B is pressed and maintained closed d. e. f. Modify the circuit in the figure to maintain the indicator ON once the two push buttons are activated. g. Add a STOP push button to turn the indicator OFF and restart the process at any time 2 L1 CR1 CR2 CR1 CR2 Indicator Figure 1.30
