SUMMARY
The discussion focuses on the BJT implementation of flip flop circuits, specifically RS flip flops, D flip flops, and JK flip flops. Users noted the decline of BJT technology in favor of MOS technology, making it challenging to find online resources for BJT flip flop circuits. The bistable flip flop is highlighted as a common divide-by-2 circuit, which requires careful adjustment of bias resistors for reliability. Recommendations include exploring online tutorials and specific circuit diagrams for practical understanding.
PREREQUISITES- Understanding of BJT (Bipolar Junction Transistor) technology
- Familiarity with digital electronics concepts, particularly flip flop types
- Knowledge of circuit design and biasing techniques
- Basic skills in using online resources for circuit diagrams
- Research BJT RS flip flop circuit diagrams
- Learn about the differences between bistable, monostable, and astable flip flops
- Explore integrated circuit alternatives for flip flop implementations
- Study biasing techniques for BJT circuits to enhance reliability
Electronics students, hobbyists, and engineers interested in digital electronics and BJT circuit design, particularly those looking to understand flip flop implementations.

There are RS (set-reset) flip flops, D flip flops, JK flip flops, and maybe a few others that have no useful function or advantage over those already given.
Which one did you have in mind?
As BJT technology has waned over the past couple two or three decades, given over to MOS technology, you may have trouble finding an online BJT equivalent circuit for a flip flop of any sort.

If you go to Google and set it to IMAGES, you can get lots of flip flop circuits.
The common one used as a divide-by-2 is the bistable flip flop.
As you can see, it uses a lot of components and also requires careful adjustment of the bias resistors. After that, it is quite reliable. I know of one that was made in 1972 and is still operating.
These days you would certainly use an integrated circuit.

You could read this description of R-S flip flops:
http://www.hobbyprojects.com/flip_flop/a_transistor_RS_flip_Flop.html
It describes this circuit:
I have several books on digital techniques, but most of them are pretty old and possibly unavailable now. I wouldn't really recommend any of them.
This is a topic where you really need to get into a class and have someone cover it for you in a logical way.
That site above is part of a bigger tutorial on digital devices here:

It seems quite well done and you might like to start there.

Good grief. I've so long heard flip-flop and bistable flip-flop used synonymously that I don't recall every hearing the term "monostable flip-flop" used-- I had to look it up to see if it really was the same thing as a one shot.
