ABSTRACT:
Crosstalk contamination of signals in a multichannel data transmission sym is designated by a matrix which has unit values for the diagonal and small values for the off-diagonal terms. If this matrix satisfies the criteria for finding an inverse thereof, the matrix may be inverted and the results are used to find the values for the correction matrix electronic circuits. The correction electronic matrix circuits with their respective inputs from the telemetry receiver give their summed outputs for each channel to be the crosstalk contamination-free signals for various channels.
