Figure 16. Channel Separation
Left-to-right cross-coupling and right-to-left cross-coupling are not exactly the same; a difference of 15 dB
is seen at 1 kHz. The channel separation is more than 80 dB in both cases. The cause for the
cross-coupling is the high impedance of the feedback network. If a lower cross-coupling is wanted, the
feedback impedance can be lowered, this has an influence on the input coupling capacitor that needs to
be equally larger and thereby adds more cost.
