"How can I use labview and the NI 4351 board to generate a 5V TTL signal or a pulse signal ."

Which is it, 6052 or 4351? If it's the 4351, then the only choice you have is to use the digital i/o lines on the board. These are intended for static i/o and, depending on your pulse requirments may not be suitable, If you have the 6052, then you have two analog outputs and the digital i/o. If you look through the shipping examples on Analog Output, you should get an idea on where to start.

The polite thing to do would be to explain why you didn't like my answer. A one star rating is the worst one you can give.
