Abstract :
Transductors with four-limbed cores have characteristics which differ from those of conventional transductors in their symmetry with respect to control-current changes. Such transductors are suitable for increasing the sensitivity of non-polarized relays and may be operated by either d.c. or a.c. signals. The suppression of response to negative signals is also possible with four-limbed transductors, and this may be used to reduce swamping effects in push-pull magnetic amplifiers subjected to large signal inputs.
