would something like this work as my detector

this is just kicking my butt

will any d flip flop ic work for this because im sure that i am limited and im not sure if the ones you have listed are available also i have not seen a program like that before what are the plots exactly its just a little confusing for me.

hi,
Which type of bistable IC's do you have to work with.??

Looking at post #21, how will that work as a detector.?

not sure got the idea while researching online and i dont think its right. And my school doesnt have any cmos chips to actually build(all TTLs) but i can build it on multisim and turn it in that way to.

TTL ICs were used 34 years to 40 years ago. I disposed of my TTL Cookbook in 1978 then bought the Cmos Cookbook and many Cmos logic ICs.
I am old and am retired. Is your teacher older than me? Get a younger teacher.
Also use a more modern SIM program (Multisim is ancient) like LTspice IV free from Linear Technology.

i wish i did have a different teacher but this is what she teaches and i am not a fan of her style or methods. And she is probably in her 30's. And i dislike multisim but it is what the school offers and i cant change it even if i wanted to. And i assume the ttl is used because that is what she teaches and that is what we have available. But even though multisim is out dated i can use it to make this work with the cmos if thats what everyone uses i just cant figure this out at all not sure why just not my thing i guess.

and another few hours and nothing not sure what to do its due Wednesday if i can get it figured out.

instead of using the ttl ics i can use the cmos i just dont know much about them but it will work better if i use the first generator that was posted.

this is also where i got the idea for the detector as it matches the signal im putting in with the generator. My only problem is i dont know what cmos ics to use to make it work.

hi,
Look at this marked up image, added the 4027 so that you can see the logic.

Note: look at the CD4013 datasheet for the pin assignments

If your teacher wants you to use old TTL ICs then use them.

 

[05gpgt2]

that would mean completely starting over and im not sure how to do it with the ttls

 

[05gpgt2]

i have the whole program wired into multisim now im haing problems getting something to show it is working like leds or something is there anything in multisim that would work for this?

 

[audioguru]

Multisim is used only in school. Most of us are not in school anymore so we don't use Multisim.

thanks for the answer but im sure there are some people that can help me out here
