Embodiment Construction
[0016] like figure 1 As shown, the specific steps of the present invention to generate the excitation signal PRMS:
[0017] 1. Assign an initial value to the seed and set the hold time. Add a pseudo-random signal to trigger the switch, the pseudo-random signal triggers the rising edge of the switch, and then assigns the initial value of 0 to the seed and sets the holding time T=300ms.
[0018] 2. Set the frequency by two. Add two on-delay timers TON1 and TON2, and the timing time is T / 2 respectively; then set the relationship between timers TON1 and TON2: TON1 first turns on delay T / 2, then turns on TON2, and TON2 turns on Then disconnect TON1 to make TON1 re-time.
[0019] 3. Set the recursive calculation of random numbers to be triggered every hold time T. In order to ensure that the calculation process of pseudo-random numbers is triggered every T time since the signal is triggered, the falling edge of the on-delay timer TON2 is added; then according to the recursive fo...
