overlap time generation

Posted on October 01, 2014 at 09:51

How can I generate two signals with a specific overlap  time between them?

I mean first signal to be square wave 50% duty cycle and the second one square wave inverse of the first one but with overlap time, that is trabsition  L->H to occur before the transition H->L of the first; and the transition H->L of the second to occur after the transition L->H of the first.

Also I want to have same frequencies.

 I was thinking in making a PWM as being the first signal

and the second to be a pulse with specific length and delay, triggered by the first signal rising edge;

Is there another way of doing this overlap?

(I) use STM32F072 disc. board)
