Input Signal：
Input Level： 80dBμV
Modulation Frequency：1000Hz
Frequency Deviation： ±22.5kHz
Center Frequency（fo）: Center frequency is measured under the
condition that modulated and 80dBμV input signal （center）
is supplied and varied its frequency. It is defined as the
frequency at that D.C.output voltage shall correspond to that for
0dBμV input signal.
Recovered Audio Voltage: It is defined as the recovered audio
voltage at center frequency（fo）.
Distortion: It is defined as the distortion at center frequency
（fo）.
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）.
