A Source of Transient Error Voltages in Switched Analog Signal Transmission
J.C. Dononvan · IEEE Transactions on Industrial Electronics and Control Instrumentation · 1971
Twisted, shielded pair cables are commonly used to carry instrumentation and control signals. Manufacturing variations can result in one of the wires of such a pair having a capacitance to the shield which is significantly different than that of the second wire. The charging of these unbalanced capacitances to a common mode voltage results in a transient error voltage on the signal pair.
