frequency at that D.C.output Voltage shall correspond to that for
0dBμV input signal.
5.2.3 Recovered Audio Voltage: It is defined as the recovered audio
voltage at center frequency（fo）.
5.2.4 Distortion: It is defined as the distortion at center frequency
（fo）.
5.2.5 Recovered Audio 3dB Bandwidth: It is defined as the difference
between the two frequencies where the recovered audio voltage
3dB from the level of center frequency（fo）.
