3bit jk synchronous counter. it counts till 5 then resets if oyuwant to remove the reset just disconnect the async reset .
sequential
circuit for a Synchronous Down – Counter circuit that counts from 1111 down to
0000. The circuit to be built using only T flip-flops
TA = QA + QB.QC.QD; TB = QC.QD; TC = QD; TD = QA'
This is a "Synchronous BCD Counter To Seven Segment Decoder" made using T flip flop .
Firstly, the counter is made using T flipflop and then its output i.e(count) is converted to digital using Seven Segment Decoder
4 bites szinkron számláló/4 bit synchronous counter with reset
A synchronous 4 bit counter. Synchronous counters don't have ripple-carry delays, just the delays through the combinatorial logic used to calculate next states.
