Cable Geometry

This refers to the relationship between conductors, both of similar polarity, and opposite
(+ and -). If this relationship is not consistent, then the electrical parameters (such as capacitance and inductance) of the cable will be constantly changing and the signal will be distorted. Conductors can be parallel, spiraled (twisted), or braided. These various geometries have certain inherent qualities. Parallel construction is inexpensive. Spirals have good RFI (radio frequency interference) rejection and usually lower inductance. Braids have good RFI rejection and low inductance, but suffer the consequences of a constantly changing electrical environment for each conductor. Too much intimacy between + and – causes overly high capacitance, braids cause magnetic confusion. It’s worth getting the cable geometry right!
