Hi I am not sure about my result so I would like to ask you if you can correct me. the circuit is composed of a counter and its outputs enter a combinational logic block. And it is this block that I am trying to simplify.
counter | outputs Q
CBA | 1 2

My circuit is working now, I think I have bad connection on my bread board and also I simply put a 10k resistor between the output of the XNOR and the input clock of the FlipFlop.
Tanks for your attention Brian.
Yes I agree I should do what you say. Look in the pic I corrected my mistake. The relay is a latching coil which requires 8mA and my buffer which has a push pull output.
Thank you but the problem append between Q2,Q1 of the CD4029 and the input of XNOR. During the change state of Q2 and Q1 the XNOR change it output for short time. I try too put cap and resistor to make a RC delay like in the pic below.
Hi everyone, I tried to design a modulo-2 to get this sequence 00,01,10,11,10,01,00. But glitch append at the ouput of the XNOR (cd4027) and trig the flipflop randomly. So do you have any suggestions to design this circuit? Thank you.
