... Fig.10) bal The suppression also depends on the accuracy of the match between Z line. The anti-sidetone network for the UBA1707 (see Fig.18) ) ast3 attenuates the receiving signal from the line before it enters the receiving amplifier. The attenuation is almost constant over the whole audio frequency range. ...
