Identify Your Electronic Components Problem prior to became the fault by using its noise

Here are the basic ideas for finding out the problems in your electronic devices, by using the noise. Noise is the first identification of the problem; using the noise types we can identify the parts in the electronic components causes the problem. Sometimes it will be solved by our self.

Thermal noise:
Thermal noise is also referred as the resistance, noise; the thermal noise comes from the thermal agitation of electronics. All electronic components have resisted so chance of thermal noise is widely found. The thermal noise reduction is possible by using the amplifier. Electric circuit elements can produce the thermal noise if they can distort energy

Shot noise:
Shot noise is associated with the current flow caused by the fluctuation of current. This noise present in both vacuum tubes and semiconductors as randomly.

Contact noise:
Contact noise is caused by fluctuating conductivity from an imperfect contact between two materials. It occurs anywhere two conductors are joined together, such as in switches and relay contacts.

Popcorn noise:
Popcorn noise is also called burst noise, first discovered from semiconductor diodes and has also appeared in integrated circuits (IC). It sounds like corn popping

For reducing these types of noises, SMBS and capacitors sometimes give quality solutions. For mechanical type noise SMBS will the solution. Some types of thermal noise can be reduced using the capacitors
