# Abstract:

Formulae are presented for torque gradient and electrical error of a simple torque system, in terms of the basic building blocks - the impedances. A simple torque system consists of a transmitter and a receiver. For this system two torque gradients are defined one observed at the receiver and one observed at the transmitter. Also a unit torque gradient is defined by the specifications. This is measured on an individual synchro independently of any connections into any system. These may turn out to be unequal. Various plausible physical assumptions are introduced from time to time to simplify results. To be specific there are five assumptions, and among these are two forms of proportionality for the impedances of two synchros of a system - a weak and a strong form. The following comparisons then hold among the various types of torque gradient 1 the unit torque gradient is equal to either torque gradient of a simple torque system of identical synchros, and 2 to develop the usual formula for either torque gradient of a simple torque system in terms of the individual unit torque gradients we require the strong form of proportionality and no effective mutual resistance.
