Phase
Description
1
On the rising edge of input E :
  • oscillation of output x for ni periods of time,
  • input x Aux changes to 1,
2
When number of periods ni is reached, output x Aux changes to 0.
If output E changes to 0 before time periods ni have elapsed:
  • the oscillation stops at the low status of outputx,
  • input x Aux changes to 0,
