Abstract
The amplification of crosstalk between two isolated circuits due to a resonant condition between the two circuits is reduced by coupling the electrical grounds associated with the circuits with a series Resistor-Capacitor network.
Claims1
A Resistor-Capacitor network for reducing crosstalk due to a resonant condition between a first circuit having a first electrical ground and a second circuit having a second electrical ground where signals of a certain quality are applied to the circuits, the Resistor-Capacitor network comprising:
- a resistor connected to the first electrical ground;
- a capacitor connected to the resistor and to the second electrical ground;
- the capacitor allowing a current to flow through the resistor during a resonant condition thereby reducing the crosstalk due to resonance between the circuits substantially without degrading the quality of the applied signals.
