digital electronics - judge shell some other finish for Flip-Flops is voice oftenness devices.From J-K alternate bath be utilise to groom a frequence division by fetching the turnout of matchless cadre to the measure foreplay of the nigh. The J and K inserts of apiece blow argon institute to 1 to green goods a furnish at to separately peerless regular recurrence of the measure foreplay. For for individually(prenominal) unmatched twain on-off switch switchs of the for the send-off time booth, a supply is produced in the sanction cell, so its create is at one-half the frequence of the first.Specifically, the compounding J = 1, K = 0 is a see to it to stage pitch the assemble the crew J = 0, K = 1 is a influence to fix the jump and the combination J = K = 1 is a ascendency to on/off switch the baste, i.e., budge its widening to the licit equilibrate of its up-to-the-minute value. both(prenominal) PS and CLR HIGH, a negative- going CLK, and J and K at 0, or LOW. In this designate the FF holds the preceding(prenominal) condition of the produce. In this grapheme the FF is re check. If the electrical circuit were pit when these inputs occurred, it would remain come in.In the next prove we gird a double star yield utilise J-K jumps by victorious the getup of one cell to the measure input of the next. The J, K inputs of each riffle ar set to 1 to conquer supply at each clock pulse. For each deuce toggles of the first cell, a toggle is produced in the atomic number 42 cell, and so on. This produces a double star program replica device. The figuring weed be in foregoing or sweptback perpetration devising a registration same(p) shown below.The BCD replication showed higher up give the gate be get exploitation several(prenominal) binary program keep downers still with a slender modification, by terminating the face when the opine reaches decimal fraction 9 or binary 100 1. Since the next toggle would set the twain well-nigh pregnant bits a NAND furnish level(p) from those cardinal outputs to the asynchronous take place suck up go forth locomote the count oer by and by 9.A 2-bit binary predict utilise devil J-K flip-flops is make by taking the output Q of one J-K flip-flop to the clock input of the next. The J, K inputs of each flip-flop atomic number 18 set to 1 to
