The signals to be distorted are connected to the input andare repeated by the receiving relay (Rec) of the device into a biasing MEASUREMENT OF TELEGRAPH TRANSMISSION 169 relay (Bias) through a network which modifies the wave-shape of thesignals and permits them to be biased easily by changing the currentthrough the auxiliary windings A and B of the Bias relay.

The manner in which bias is produced will be understood morefully by reference to Fig. 19 which shows graphs of the currents in the J (I).
