  Hello i am trying to design a 4-bit counter that will count like the following sequence :
  
  1,3,6,9,C,D,1,3.......so on.
  
  Can anyone help me?

  Hmm, how far have you progressed?

  U can solve it using K-map, find J and K (inputs) for every flip flop....

  Hi,
  
  For 4 bit binary ring counter#-Link-Snipped-# is used. But you want odd no. why??

  There are even number too like 6,C. May be he want some counter that repeats specific digits. 😀
