5. 6. En S R This can also be tried with 5 NOT gates in series if three is not working. Circuit # 3 Start with the EN, S & R inputs low. Enable the circuit by manually pulsing the EN input switch from LOW to HIGH, and then returning to LOW. Carry the circuit through its truth table shown below and confirm proper operation. En SRQ Q Mode of Operation 100 ↑01 ↑ 10 ↑ 11 In the previous circuit whenever the EN was HIGH any change in the S & R inputs was immediately passed to outputs. In the edge trigger circuit the state of the inputs should pass to outputs only when the EN input is pulsed LOW to HIGH. Changing the S & R inputs while the EN is held HIGH should not affect the outputs. To confirm that the change in output is occurring on the edge of the pulse and not the HIGH level, with the EN input LOW, set the S input HIGH, and the R input LOW. Take the EN input HIGH. The Q output should now be HIGH also (SET mode). Now with EN still HIGH, change S to LOW and R to HIGH (RESET mode). Did the flip-flop change to RESET mode? Pulse the EN input LOW and then HIGH again. Now is the flip-flop in RESET mode?

Question
Do the truth table of circuit #3 and answer the two questions in the bottom of the paper. Thanks
Circuit #3 En S This can also be tried with 5 NOT gates in series if three is not working. 5. Start with the EN, S & R inputs low. Enable the circuit by manually pulsing the EN input switch from LOW to HIGH, and then returning to LOW. Carry the circuit through its truth table shown below and confirm proper operation. En S R Q| Q ↑ 0 0 Mode of Operation ↑ 0 1 ↑ 1 0 ↑ 1 1 In the previous circuit whenever the EN was HIGH any change in the S & R inputs was immediately passed to outputs. In the edge trigger circuit the state of the inputs should pass to outputs only when the EN input is pulsed LOW to HIGH. Changing the S & R inputs while the EN is held HIGH should not affect the outputs. 6. To confirm that the change in output is occurring on the edge of the pulse and not the HIGH level, with the EN input LOW, set the S input HIGH, and the R input LOW. Take the EN input HIGH. The Q output should now be HIGH also (SET mode). Now with EN still HIGH, change S to LOW and R to HIGH (RESET mode). Did the flip-flop change to RESET mode? Pulse the EN input LOW and then HIGH again. Now is the flip-flop in RESET mode?
