Design a 4-bit synchronous counter that counts in 2,4,2,1 code. The counter shall count all Odd numbers in the 2,4,2,1 code. Use the minimum number of clocked JK flip flops and any necessary logic gates to build this counter. Note: treating the unused state don't care con dition s. 1. Write down the excitation table of the JK flip flop. 2 Draw the state diagram of the counter 3. Specify how many flip flop required to build this counter (explain your answer)? 4 Write down the transition table. 5 Use k-maps to find the equations of the flip flop inputs. 6. Plot the logic circuit of your counter.

Which of the following statements about equipment grounding conductors (EGCS) is true? A. The National Electrical Code permits the EGC to also perform as a grounding electrode conductor. B. More than one EGC must be used if multiple circuits are installed in a single raceway, cable, or cable tray. C. No current should be present in the EGC during normal operation. D. EGCs are required to be decreased in size to address voltage drop.
