Part IV-T Flip-Flop Background AT Flip-Flop is a flip-flop whose output toggles between HIGH and LOW on each clock pulse when input T is active. A T flip-flop can be constructed using a D flip-flop. Procedure

1. Add a block diagram sheet to the project and draw the logic diagram of a T flip-flop using D flip-flop from Part III. o You will need to create a block diagram of your D flip-flop.

2. Compile the project.

3. Experimentally find out the excitation table of the built T flip-flop

A T flip-flop is a type of flip-flop that toggles its output between HIGH and LOW states on each clock pulse when the input T is active. A D flip-flop can be used to construct a T flip-flop by connecting its output (Q) to its input (D) through an XOR gate, with the input T connected to one input of the XOR gate.

To draw the logic diagram of a T flip-flop using a D flip-flop, we can use the following steps:

1. Draw the block diagram of a D flip-flop, which typically includes an input D, a clock input, a set input, a reset input, an output Q, and an output Q' (the complement of Q).
2. Draw an XOR gate and connect its two inputs to the input T and the output Q of the D flip-flop, respectively.
3. Connect the output of the XOR gate to the input D of the D flip-flop.
4. Connect the clock input to the clock input of the D flip-flop.
5. Connect the set and reset inputs of the D flip-flop to HIGH (i.e., the voltage level that represents logic 1).
6. Label the output of the D flip-flop as Q and the complement of Q as Q'.
7. Label the input T as T.

Once the logic diagram is drawn, we can compile the project to make sure there are no syntax errors or design rule violations.

To experimentally find out the excitation table of the built T flip-flop, we need to test the behavior of the flip-flop for all possible input combinations. For a T flip-flop, the input T can be either HIGH (1) or LOW (0), and the clock input can be either rising or falling edge-triggered. The excitation table shows the output behavior of the flip-flop for each input combination.

We can create a truth table to record the input and output states for all possible input combinations. For example, if we assume that the flip-flop is initially in the LOW state (Q=0), we can create a truth table as follows:

T	Clock	Q (output)
0	rising	0
0	falling	0
1	rising	1
1	falling	1

From this truth table, we can see that when the input T is LOW, the output Q remains unchanged regardless of the clock input. When the input T is HIGH, the output Q toggles its state on each clock pulse.

Based on the truth table, we can construct the excitation table that shows the input and output behavior of the T flip-flop for all possible input combinations. For a T flip-flop, the excitation table can be summarized as follows:

T	Q (output)
0	Q(n-1)
1	~Q(n-1)

where Q(n-1) is the output state of the flip-flop in the previous clock cycle, and ~Q(n-1) is the complement of Q(n-1).
