4. Build and simulate in Multisim the state machine in (3). You can start with the incomplete circuit in Figure 9 where the circuit diagram of the state equation s3(t + 1) is already wired. You can use 4- input and 3-input AND gates like 74LS21N and 74LS11N, respectively. They can be found under TTL -> 74LS. Use 7432 for OR gates and 7404 for NOT gates (both are also under TTL -> 74LS). Connect a clock (under SOURCES -> DIGITAL_CLOCK) to pin 11 of the 74LS374N (under TTL->74LS_IC) and set the clock frequency to 50Hz. Take a screenshot of your circuit.
