Electrical Noise Affecting Sensitive Electronics generally speaking are common mode noise and if care is nit taken then these noise do become normal mode noises and affect measurement.

his article by Jerry Gaboian is very interesting one.

Such transient noises are always there. BY use f proper filter some of them can be reduced but if your signal is in same frequency bnd then sometime you have to live with them. Trace in green has reduced noise due to 20MHz BW filter.

I did lots of experiments and then I found somewhat similar results. Trace below is my actual signal and noise is almost in same frequency bands. It has high frequency edge andslow decay.

Some noise signals are so bad.
