Hello,
This has been a trouble for me for years.
Sometimes I observe several types of noise on signals or power supply outputs such as spikes, ringing, hum ect.
But I cannot tell whether what I see it is due to common mode interference or differential mode.
Is there a quick way or measurement method to check the nature of the noise in such cases? (Like cutting the earth link from the scope ect.)
Can you give an example of measurement way so one can conclude the noise he sees is CM or DM?
Thanks in advance,
