From J-K flip-flop can be used to build a frequency divider by taking the output of one cell to the clock input of the next. The J and K inputs of each flip-flop are set to 1 to produce a toggle at each cycle of the clock input. For each two toggles of the first cell, a toggle is produced in the second cell, so its output is at half the frequency of the first.
Specifically, the combination J = 1, K = 0 is a command to set the flip-flop; the combination J = 0, K = 1 is a command to reset the flip-flop; and the combination J = K = 1 is a command to toggle the flip-flop, i.e., change its output to the logical complement of its current value.
Both PS and CLR HIGH, a negative-going CLK, and J and K at 0, or LOW. In this condition the FF holds the previous condition of the output. In this case the FF is reset. If the circuit were set when these inputs occurred, it would remain set.
In the following experiment we build a binary counter using J-K flip-flops by taking the output of one cell to the clock input of the next. The J, K inputs of each flip-flop are set to 1 to get toggle at each clock pulse. For each two toggles of the first cell, a toggle is produced in the second cell, and so on. This produces a binary counter device. The count can be in forward or backward direction making a modification like shown below.
The BCD counter showed above can be build using several binary counters but with a small modification, by terminating the count when the count reaches decimal 9 or binary 1001. Since the next toggle would set the two most significant bits a NAND gates tied from those two outputs to the asynchronous clear line will start the count over after 9.
A 2-bit binary counter using two J-K flip-flops is done 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 are set to 1 to ...Download file to see next pagesRead More

Digital electronics logic gates

...Digital Electronic Logic Gates – Lab Report Objective In this lab activity, the purpose was to use the NOR and NAND gates to implement several basic logic gates, and use the pulse waveforms to test XOR and OR gates. Additionally, the experiments aimed at using the XOR and OR gates to setup a circuit that implements 1’s and 2’s complement of a 4-bit binary number. We used two ICs to determine whether an IC had a NOR< NAMD, XOR or OR gates so that we could know exactly where the outputs and inputs of the ICs were. The NAND and NOR gate was first utilized to implement the other basic logic gates and then the XOR and OR gates were tested using the pulse waveforms. The same gates were again used to setup...
