Fig.3 Equivalent impedance circuit
The anti-sidetone network for the UTCTEA1062N/TEA1062AN family shown in Fig.4 attenuates the signl received
from the line by 32 dB before it enters the receiving amplifier. The attenuation is almost constant over the whole
audio frequency range. Fig.5 shows a convertional Wheatstone bridge anti-sidetone circuit that can be used as an
alternative. Both bridge types can be used with either resistive or complex set impedances.
