Side tone coupling circuit diagram


Posted on Feb 7, 2014

Side tone coupling:In telephones, it is the hearing of one`s voice in the receiver when one speaks. Too muchside tonemake people speak lower and can cause feedback. Too littleside toneand people may think the phone is not working or may shout. Figure This is a simplified schematic diagram of a receiver sidetone circuit. Because curren

t will not flow through a balanced circuit, the turns ratio of inductors L1 and L2 is unbalanced by a predetermined amount and the value of resistor R is changed so as not to match the line impedance. This way, a controlled amount of signal can be induced into L3 to be used as receiver sidetone.
