Introduction<br />

In the previous example, the two Boolean <strong>Logic</strong><br />

equations were broken into Product terms.<br />

Each P-term was then programmed into the<br />

P-tenn section of the PLA Program Table. This<br />

was accomplished in the following manner:<br />

Step 1<br />

Select which Input pins 10 - 115 will correspond<br />

A - G are the input variable names. 16 through<br />

10 were selected to accept inputs A - G respectively.<br />
