About this calculator

Overview

Crosstalk is unwanted signal coupling between channels or circuits. Measured in decibels (dB), higher negative values mean less interference. Critical for audio quality, data integrity, and signal isolation.

💡

Pro Tips

Shielded cables reduce crosstalk significantly.
Twisted pair wiring cancels electromagnetic interference.
Increase cable separation to reduce capacitive coupling.
Ground loops are a common crosstalk source.

Fun Facts

"Professional audio requires -80 dB or better crosstalk."
"CAT6 Ethernet specifies 45 dB crosstalk at 250 MHz."
"Near-end crosstalk (NEXT) affects data transmission most."
"Stereo separation is essentially crosstalk measurement."

Formula: Crosstalk (dB) = 20 × log10(Victim Signal / Interfering Signal)
