Used Sb74293 Depicted Page 456 Figure 714 Configured 4 Bit Counter Analyse Assignment Use Q37086990

We used an SB74293, depicted on page 456, Figure 7.14. Weconfigured it as a 4 bit counter to analyse it.

Your assignment is to use the counter as a 3 bit counter bysimply using the 3 lower flip-flops (QB,QC and QD) and using INPUTB as the clock of the circuit. You are to analyse the behaviourwhile assuming that the flip-flops are all POSITIVE EDGE TRIGGERED(remove the inverter that is in front of all clock
