PWM

Hello all,
I am new to microcontroller and to this forum.It seems I have a conceptional problem in PWM generation.

My Idea is:PWM module gemnarates a square wave which has the peak value 5 volt and low value 0 volt.I can set pulse period (and hence frequency) and pulse width using PPx and PWx registers respectively.The average voltage output which I get out of it is:5xduty cycle ratio.

If I change pulse width, I change duty cycle ratio.

Now,can I treat this output as an analog voltage?Can I run a device which needs analog voltage with this PWM output (even if I do not filter it)?

Could you please clear my confusions up?

(I am sorry for my elementary questions)

Regards,
Denis
