### Flip-flop Conversion – D flip-flop to T flip-flop

Here you would see how to implement a T flip-flop from D flip-flop step by step – “Flip-flop Conversion – D flip-flop to T flip-flop”.

__Flip-flop Conversion – D flip-flop to T flip-flop__

### Step 1: Write the truth table of the required flip-flop

Here the
required flip-flop is T flip-flop

Hence
you need to write the truth table of T flip-flop which is

T |
Q |
Q |

0 |
0 |
0 |

0 |
1 |
1 |

1 |
0 |
1 |

1 |
1 |
0 |

### Step 2: Write the excitation table of the given flip-flop

In this
case the given flip-flop is D flip-flop

Therefore
you need to write the excitation table of D flip-flop which is

Q |
Q |
D |

0 |
0 |
0 |

0 |
1 |
1 |

1 |
0 |
0 |

1 |
1 |
1 |

Step 3:
Write the conversion table

The
conversion table, which is a combination of truth table and excitation table, to
implement a T flip-flop from D flip-flop is as follows

T |
Q |
Q |
D |

0 |
0 |
0 |
0 |

0 |
1 |
1 |
1 |

1 |
0 |
1 |
1 |

1 |
1 |
0 |
0 |

### Step 4: Find the Boolean expressions for the inputs of the given flip-flop

In this
case the given flip-flop is D.

Therefore,
write the Boolean expression for D from the conversion table using K-Map.

K-Map
for D:

Expression
for D would be

D = T^{/}Q_{N}
+ TQ_{N}^{/}

### Step 5: Draw the circuit for implementing T flip-flop from D flip-flop

For
this, connect the input D of the given flip-flop (D flip-flop) to the circuit
made for the expression of D obtained from the K Map. Therefore, the circuit
would be:

In
this way a T flip-flop can be implemented using a D flip-flop. Hope this post
