added to the wanted signal level of 10 uV, the unwanted
signal input voltage suppressing output of the wanted
signal by 3 dB is 10 mV or more.

of 10 uV and an unwanted signal level of 1 mV
separated by 500 Hz
Overall distortion and noise
When an input signal level of 30 uV is applied, the ratio between
low-frequency output 1000 Hz and unwanted components contained
in that output is 30 dB or more.
