Detailed explanation-1: -Crosstalk is typically stated in decibels (dB). Crosstalk should normally be measured as a function of frequency, since the values are likely to vary strongly with frequency. The most common circuit mechanisms causing crosstalk are stray capacitive and inductive coupling.
Detailed explanation-2: -Crosstalk interference is an undesirable phenomenon in communication channels. It happens when the signals from one line pick up with a signal in the neighboring line, and it can greatly affect the privacy of communications.
Detailed explanation-3: -Equal level far-end crosstalk (ELFEXT) can be defined as the ratio of desired received signal to the unwanted crosstalk at the far end. Above a certain break frequency, the ELFEXT value increases with dual-slope behavior (40dB/decade), and this second-order effect on ELFEXT is known as the dual-slope effect.
