Abstract
Active impedance compensation is accomplished in a bus system by means of a variable capacitor element associated with a connection circuit between system slave devices and an impedance balanced channel. The variable capacitor elements may be programmed using a control value determined by actively exercising the channel with a telemetry signal and evaluating the resulting signal reflections which are indicative of the impedance discontinuities on the channel.
