    Hi. Can anyone help me with a 6 bit ring counter circuit? Ive searched the net and only 4 bits are available. Ive tried to add another flip flop but the output is not a ring counter. Can someone help me with this. I will use it to our project. Thanks

    Can you post the circuit you have that works?

    I tried this circuit and it work but I need a 6 bit ring counter. I tried to add two flip flops but the output is not a ring counter anymore. Could you help me to modify this circuit to have a 6 bit ring counter? Thanks for complying.

    It should be quite simple to add any number of flip flops to extend a ring counter. We can't help until you show us the schematic of what you are trying.

    I'm building an Amplitude Shift Keying with a 6 bit square wave input using a Flip Flop circuit for my school project. Is this circuit right? Is the Flip Flop circuit right for my 6 bit input? Can anyone help me with this? Thanks.

    How does ASK relate to a 6 bit ring counter? Can you explain in some detail what you are trying to achieve?

    i used the 6 bit ring counter as a digital input. I connect the ring counter to the switch so that I can adjust the square wave signals. Example I want to encode a 101101. I open the 2nd and 5th switch to the ring counter and short the 1st, 3rd, 4th, and the 6th switch to have a digital input of 101101. Is my idea wrong?

    You are trying to use the ring counter the wrong way. A ring counter is a kind of shift register - http://en.wikipedia.org/wiki/Ring_counter

    You are apparently trying to read the state of a set of switches. There are several ways to do this, but there is not enough information without a schematic.

    All your flip flops have their SET and CLEAR inputs floating. U1 has several floating inputs. No logic can function properly like that. All unused inputs must be tied low of pulled up high for proper operation.
