How to make a circular circuit?

[yujeong]

Hello, I would like to create a 191 circuit that repeats 1-9-1-1-9-1-1-9-1... I would appreciate it if you could give me some ideas on how to make it. Right now, I can only make circuits like this...

Ladies and Gentleman, today’s winner for Most Unintelligible Post.

Congratulations, Yujeong!

For those who lack the imagination.... or experience in reading a translated ESL question.

This reminds me when we invented an ISDN over T1 in '79, which included digital Telephony with dial-pulse and DTMF. So I wanted to simulate dialing 999-9999 then do on-hook, pause, go off-hook , pause and repeat the dial pulses.

Except it appears you want to repeat dialing 911 911 911 in decimal pulse trains.

Is that right ?
Or do you just want a BCD sequence of 911 repeating parallel 4 bit binary bits?

Hi,

I´m the next person who has no idea what you want to achieve .. and what exact problem you see.

I always wonder why people don´t draw a simple sketch (maybe by hand).
A sketch does not need to be translated ... and usually tells more than a lot of text.

There are several ways to do this. You would need a mod-3 counter (0-1-2-0-1-2-0-1-2-...), then you would connect a custom 2bits-to-4bits decoder to obtain 1-9-1 from the 0-1-2, respectively.

To design the decoder, you need to use the truth table and then derive the logical expression for each of the four output bits based on the combination of the two input bits.

Since this enigma is posted in the ASIC section, I suppose the post author is not familiar with finite state machines.

This has nothing to do with imagination or experience or translation, and certainly nothing to do with some project you worked on 45 years ago.
There is nothing in the OP’s post to indicate that they want to be “dialing 911 911 911 in a decimal pulse train” as you infer. And, if you read the post, you’d understand that they want 191, not 911. Perhaps your lack of imagination or experience is at fault.
Maybe they want to blink a light in a 1-9-1 sequence. Maybe they want a numeric display that flashes 1-9-1. There’s no way of knowing.
The only thing I can infer from the OP is that they are too lazy to post a complete question. They actually demonstrate this by stating “I can only make circuits like this...” followed by…nothing.

Here is an ASIC in a circular circuit board.
If you want a cyclic decimal pattern "191", you must define the inputs and the outputs in more detailed specifications. with timing information.
