slackjack Posted December 2, 2005 Report Share Posted December 2, 2005 Hey guys,I'm trying to design a counter using FF in multisim. I know that I clock signal must come along to for any change to occur in the circuit (I'm forgetting about CLEAR and PRESET for now). What should I use as the souce of the clock in multisim? And another question, what exactly is the source of a clock signal (in a real circuit)? If I open an close a switch, does that create a clock pluse (square wave) that an operate the FF?--thank you. 8) Quote Link to comment Share on other sites More sharing options...
slackjack Posted December 6, 2005 Author Report Share Posted December 6, 2005 I think I figured it out. I will have to use a 555 timer to generate the clock pluse. I will also need a POT to adjust the resistance and that would change the frequency of the pluse. Quote Link to comment Share on other sites More sharing options...
