What is within the phono signal in terms of transfer function

Posted by Busybusy on August 13, 2003 at 08:58:26:
Hi,
As the phono signal supposedly is corrupted with crosstalk, and limited separation, what would be the transfer function that truly represent the phono signal?
Assuming ignoring the RIAA curve,
L (left output) = L + k*R ? (k is a constant)
Assuming that we know or find the k, then can't we inject a -k*R into the L signal?
L = L + k*R - k(R+k*L)=L - *k^2L, therefore, we eliminated the crosstalk and increase separation? Assuming symmetry in mechanical system (well designed hardware), then k in L and R signal should be the same.
This would be easy to incorporate into a phono stage?
Any thoughts?
