Luke Wyatt Sequential Switching Circuits 16/11/07 Sequential Switching Circuits Risk Assessment The experiment had some very low risks. These are outlined below 1. Electrical Test 1 The truth table for the gate and the Boolean equation is shown on the lab sheet and is a NAND gate. Test 2 The results show that when the circuit is initially in state A to change it to state B, S needs to be switched. Inversely to change from state B to state A R needs to be switched. When the circuit is in state A, switching R has no effect on the state. Similarly when the circuit is in state B switching S has no effect on the state. Test 3 The experiment proves the truth table to be correct, and it can be said that if G=0, then Q+=Q, and if G=1 then Q+=D. A change of state will be observed only if G= 1, and D=D. This is an example of an asynchronous sequential circuit. Test 4 The experiment proves the truth table to be correct. Test 5
