Digital Techniques and Microprocessor Notes

Binary half and full subtractor are designed by solving K-MAP. 

Here half adder and full adders are designed by solving K_MAP. 

For binary to gray code conversion please refer gray codes post. 

In k-Map representation we can group pairs, quad and octet only.

K-MAP solving is a graphical method of simplifying boolean equation. To represent K-MAP gray codes are used. 

NOR-NOR Implementation is same as NAND-NAND implementation.only difference is .... 1. convert given expression in POS form. 2. Replace OR gate by NOR gate. 3. Replace NOT gate by NOR inverter.

NAND -NAND implementation is very easy . Here i am giving some key points to remember. 1. convert given expression in SOP form. 2. replace AND gate by NAND gate. 3. replace NOT gate by NAND inverter.
