oh what i meant by better is a circuit that fulfill the same requirements & yet using less components & gates .. that would mean faster & more efficientIn order to answer the first question you need to define what "better" means. This circuit has been known for 50 years or more and the definition of "better" has changed at least three times over that period.
The answer to the second question is "if you can get the requirements clear" you can crank out a design that "meets the requirement". From there you apply the process of stepwise refinement until it is a good as it needs to me
The "minimum number of gates" was the standard of better from about 1952 to about 1970. Once integrated circuits were fabricated, it changed to the "minimum number of packages" on a board. Nowadays you can cram so much logic into an FPGA it is not worth the "expensive engineers" time to look for improvements at the gate level. You write a verilog or VHDL script and the software does the optimization. That is why I said the definition of "better" has changed at least three times since the first computer was built.oh what i meant by better is a circuit that fulfill the same requirements & yet using less components & gates .. that would mean faster & more efficient
This is faulty reasoning. It is synchronous because the state outputs change in response to the same clock signal. Also, if Clk is high all the time, then the outputs will never change at all (unless you take the Clear LO, since it is an asynchronous input -- probably). These JK Flip Flops (JKFFs) are positive-edge triggered, meaning that the J and K inputs are sampled and the output value updated in response to a rising edge (LO-to-HI transition) on the Clk input.because this is a synchronous counter then we will assume that Clk is at logic high (1) all the time
That is a really loaded question (and one of my pet peeves with most textbooks and many instructors). Rest assured, none of what I am about to say is directed at you -- it is a perfectly reasonable question for a student to ask. My problem is when text books or instructors just tell students to "simplify" something or to make it "better" or to "optimize" something without specifying by what metric "simple", "better", or "optimal" are to be measured -- and, yes, I am still guilty of it occasionally myself, but I think I have gotten pretty good at catching myself.1-is there is a better design for such circuit
Studying them is a very good start. Study as many different circuits as you can. Learn how an edge-triggered flip flop is actually constructed (and there are three common ways that are markedly different). Learn what adders and multipliers and seven-segment decoders and binary counters and gray code counters are and how they work and what they are used for. The more circuits you have been exposed to and understand, the bigger your toolbox will be when it comes to designing your own circuits.2-what should i do to acquire the skill of designing circuits like this rather than just studying them ?????
My pleasure. I enjoy helping anyone that is truly willing to put forth the effort to learn.i'm really very grateful to u WBahn ..
