Fig.13 Test circuit defining voltage gain of MIC+,MIC- and DTMF inputs.
Voltage gain is defined as : GV=20*log(|VO/Vi|).For measuring the gain from MIC+ and MIC- the MUTE input
should be HIGH(UTC TEA1062 is LOW) or open-circuit, for measuring the DTMF input MUTE should be
LOW(UTC TEA1062 is HIGH) .Inputs not under test should be open-circuit.
