how to design a h bridge with p and n channel mosfets?/////////help needed?actually the real problem is how to design gate resistors?

Mayby it would be wise to check previous posts.. there is a topic of how to control a 9V motor or something like that, where i posted an drawing of two H-bridges.

http://www.geocities.com/fet_h_bridge/h-bridge.htm is also a link of some theory of an H-bridge, it is well worked out to give you an image of how it works. First i wanted to make his drawings, but after i bought a book of robotics i realised it could be done much more easier.

take a look around to find my drawing.

thanks a lot ...
is it possible to avoid shoot through problem by designing the gate resistance properly.i mean in considering their on and off time plus frequency of switching.
