Pulse generation: When a certain part of the nerve is stimulated with sufficient intensity, an action potential is generated in this part, and it propagates in two directions along the nerve fiber from this point. According to the main position of the pulse, it is an organ that acts from the center to the end in the centrifugal nerve, and it conducts from the terminal receptor to the center in the centripetal nerve to generate the pulse.

The classification of pulses are:
1, pulse dialing
Is a time domain processing method, using the number of pulses to represent numbers. Pulse dialing mode has strict requirements on pulse width, size, spacing and shape. If these parameters change due to line interference or other reasons.
2. Pulse power supply
The user's load needs to be powered on intermittently, that is, according to a certain time law, the load is powered on for a certain time, and then powered off for a certain time, forming a cycle. This repeated execution constitutes a pulse power supply. For example, in the aging process of non-polar electrolytic capacitors, it is necessary to charge the capacitors forward for a period of time.
3. Electromagnetic pulse
Electromagnetic pulse (EMP) is a powerful energy field generated instantly, which is very sensitive to energy waves and can destroy countless power systems and high-tech microcircuits in the distance. The explosion of nuclear weapons in the upper atmosphere can produce a huge electromagnetic pulse effect, which is the phenomenon of high-altitude electromagnetic pulse (HEMP).
