1/3 Octave Filter Linearity

The linearity of the 1/3-octave filter has been measured for both ranges (low and high). The

experimentation is done with an adaptor (ADP092) and an electric signal. The results in dB are for an

input sensitivity of 50 mV/Pa. The maximum and the minimum linear levels are measured for each

1/3 octave band along with the noise floor.
