Dear Sir,

I connected power supply like that only.Ground was common. But that was not the problem.I connected back the supply as earlier in parallel.

As you said, problem was that ripples.When I connected a 1000uf(25V) capacitor  in parallel with Vs Pin(12V) and the Ground pin of  L293D, the problem was solved.

Thanks for your support.

Rgds,

George
