so that negative resistance+positive resistance=no noise

1. the negative resistance is when you increase the voltage after some specific value the current starts to decrease. If this is the case then as you see that the current is decreasing then the power will not be increasing so noise will not reduce in this case.
2. If it is like that due to some reason at the last instances the power of the input is increasing then it will definitely reduce the noise.(The negative resistance phenomenon may be observed in many well-known everyday situations where something (a being, a device etc.) containing an additional power source affects (as a proportional reaction of some disturbance) something else containing the main power source) OR (The additional source may help or impede the main one in three degrees (under-, exact- or over-). Negative resistance represents the last degree when the additional source "over-helps" or "over-impedes" the main one.)
Noise amount is determined with noise power which is equal to (noise amplitude)², and this is always posistive no matter which sign has amplitude.freetofree said:Do you think there exists negative noise? Or, all the noise is positive.
