Abstract
A clock signal having a clock pulse width duration is received. A delay time is received. A first relationship and a second relationship between the clock pulse width duration and the delay time are determined. A new clock is generated that has a first new clock pulse width duration determined by the first relationship and the delay time and a second new clock pulse width duration determined by the second relationship and the clock pulse width duration. Switching between the first new clock pulse width duration and the second new clock pulse width duration is automatic based on the first relationship and the second relationship.
