questions 2,3,4 more information is not needed. thanks.

1) In lecture we went through the design of an arbitrary count sequence (7, 4, 9, 13, 11, 7, 4, ....). We showed that 'O mapped into '13'. Complete the state diagram showing the mappings for the rest of the numbers not in the main count sequence. 2) Using a 54HC162 counter design a module-9 counter. 3) Design a counter whose main count sequence is all non-prime numbers less than 16. You do not have to provide a schematic. It will be sufficient to just provide the excitation equations. 4) Assuming you are using 74LVC2G74 registers, would a 10-bit ring counter or a 9-bit twisted- ring counter have a higher possible clock frequency. Justify your answer. 1) In lecture we went through the design of an arbitrary count sequence (7, 4, 9, 13, 11, 7, 4, ....). We showed that 'O mapped into '13'.
