* Question
| What types of impulse noise are there? |
* Answer
| (1) The periodic impulse noise of a synchronous AC power source is a type of noise wave composed of a series of pulses of the same or double the power supply frequency.A typical cause of this noise is the inclusion of a silicon controlled rectifier or a thyristor based dimmer.
(2) Asynchronous cyclic AC power supply synchronized with AC power supply The periodic impulse noise is a series of noise waves composed of a series of pulses having a higher frequency than the power supply AC.A typical generator of this type of noise is a switching regulator. |
