It can be seen that the external clock pulses (pulses to be counted) are fed directly to each J-K flip-flop in the counter chain and that both the J and K inputs are all tied together in toggle mode, but only in the first flip-flop, flip-flop A (LSB) are they connected HIGH, logic "1" allowing the flip-flop to toggle on every clock pulse. Then the synchronous counter follows a predetermined sequence of states in response to the common clock signal, advancing one state for each pulse.
The J and K inputs of flip-flop B are connected to the output "Q" of flip-flop A, but the J and K inputs of flip-flops C and D are driven from AND gates which are also supplied with signals from the input and output of the previous stage. If we enable each J-K flip-flop to toggle based on whether or not all preceding flip-flop outputs (Q) are "HIGH" we can obtain the same counting sequence as with the asynchronous circuit but without the ripple effect, since each flip-flop in this circuit will be clocked at exactly the same time. As there is no propagation delay in synchronous counters because all the counter stages are triggered in parallel the maximum operating frequency of this type of counter is much higher than that of a similar asynchronous counter.

Design a synchronous 4-bit binary counter?
http://ftp.csci.csusb.edu/schubert/tutorials/csci310/f03/dw4bit.pdf
How do you design the 3 bit binary counter using D flip flop?
Designing a 3 bit synchronous counter using jk flip flop is not an easy project for the uninformed. This is best left to professionals who are adept at programming. There are lengthy guides available on the internet if it is necessary to create one.
No of flip flop in 5 bit ripple counter?
There are five flip-flops in a five-bit ripple counter.
What is a 2 bit counter?
a 2 bit counter is a counter which have only 2 bits i.e. the posibble counting states are 00, 01, 10,11,00. It may also be known as MOD 3 counter. It can be realized by using 2 Flip flop.
Why program counter and stack pointer is 16- bit?
Because that's how Intel designed it. Even though the 8085 is an 8-bit computer, the program counter and stack pointer are 16 bits wide in order to support the address bus, which is also 16 bits wide. In the case of the 8086/8088, the program counter and stack pointer are still 16 bits wide, even though the address bus is 20 bits wide, because the 8086/8088 adds segmentation through the 16 bit segment register which is left shifted by 4.

Explain the working of 4-bit binary synchronous counter.?
One jk flip-flop with j=k=1 should be added to the system so that it's modulus becomes 16 instead of 8.
How does a digital countdown timer works?
a digital countdown timer is simply a digital synchronous counter consisting of registers and flip flops example :to count the number from 0 to 15 we require a four bit synchronous counter which will pass to sixteen stages continuously with shifting from one stage to other after every clock pulse and the cycle continues

Design a mod-7 synchronous counter using JK Flip-Flops?
You do it by studying, and doing your homework by yourself instead of trying to get someone else to do it for you.

What is the maximum counting speed of a 4 bit binary counter which is composed of a flip flop with a propagation delay of 25nano seconds?
Assuming you are running in synchronous mode, a counter with a propagation time of 25 ns can run up to 40 MHz. Since there are other gates involved, I would consider a margin of safety to be 20 MHz.
What is 4 bit counter?
