Isolation

Isolation is the ability to keep a signal on an unused channel from appearing on an active, terminated channel. Isolation is specified in dB of rejection, according to one of the following equations:

Isolation (dB) = 10 log (P_source / P_out)

Isolation (dB) = 20 log (V_source / V_out)

The following figures illustrate isolation.
