Hello,
Have always had trouble in "understanding" db the right way.
e.g., when I look at attenuation charts for the various coax, the losses are always given in db.
Is this a db voltage, or db power loss ?
How would one know ?
e.g., if I see a loss at some freq. of 3 db, does this imply that I am "losing"
about 30 % of the signal, or,... ?
If someone might explain all of this, would be appreciative.
Thanks,
B.
