The serial input of the register is done with the toggle switch via the OR gate.ĥ 4. (b) Modify your circuit from part (a) as shown below to implement a "rotate" capability in the register by connecting the Q 0 output back to the input through an OR gate. Note that the JK flip-flop in the editor does not contain the output Q', but it can be obtained by inverting Q (attach an inverter to Q and use the output of the inverter as Q').
Using toggle switches to provide the clear input as well as the serial input.

Experiment with this circuit using a low frequency clock input provided by the function generator so that you can observe the register output patterns Q 3 Q 2 Q 1 Q 0 on LEDs. The preset inputs should be tied to logic HI. Note that an inverter is required only for the left-most flip-flop thereafter the Q' output is available instead. A simple left-to-right shift register can be constructed from JK flip-flops configured as D flip-flops as shown in the circuit below.

Shift registers (a) Flip-flops can be connected in series to form shift registers in many ways. For each circuit, load into the MAX3000 chip and test on the bread board using LED's and switches.Ĥ 3. For the remainder of this lab, design the required circuit using the graphic design editor (Appendix B, page 832) included in the Quartus II design package. Registers can be forced to zero by the simultaneous application of a pulse to the asynchronous clear inputs of each flip flop that comprises the register. We will study the behavior ofģ some examples below. Shifting all bits one position to the left multiplies the register contents by 2 each shift to the right divides the register value by two. Another common example is shifting in which the values of individual bits are passed from one position of the register to another. For example, an n-bit counter may be considered a register with the capability to increment (or decrement) its value. However, registers may also be considered to be operational meaning that the value they hold may be altered in response to an external input. the D inputs of D flipflops) in response to a "write" command (the clock pulse).
The simplest form of a register is used to just capture and hold a value applied to its inputs (eg. A single flip-flop can be considered to be a single-bit register. Registers and Counters A register is a group of n flip-flops operating together whose outputs are considered to represent an n-bit binary number. Connect the J and K inputs together and verify that it operates as a T flip flop and write its characteristic table. Connect an inverter between the J and K inputs and verify that the operation is that of a D flip flop. Use toggle switches for the inputs and LEDs on the outputs.
Note carefully the clock edge to which it responds as well as the asynchronous operation of the preset and clear inputs. It is versatile in that it may be easily used as a toggle flipflop ( T-type) or a D flipflop (D-type) (a) (b) (c) Carefully verify the behavior of the JK flipflop (in the 7476 TTL package) and write out its characteristic table. The JK flip flop is a widely used Master-slave device that features in the design of many sequential circuits. Using switches and LEDs, carefully verify their operation and write their function tables. Construct the circuits for the RS latches shown below using the 7400 TTL package. The RS latch is the fundamental element in sequential logic design. Bring your textbook to the lab!
