(1) One octave marked
*
indicates a change from the initial frequency to double or half
frequency. For example, any of the changes from 10 Hz to 20 Hz, 20 Hz to 40 Hz, 40 Hz to
20
Hz,
and 20
Hz
to 10 Hz are referred to as one octave.
(2) The noise durability and dielectric withstand voltage values were obtained with the RS-232C
and RS-422 interfaces unconnected.
