General Specifications
General specifications for the transmission converter are indicated in
Table 3.1.
Table 3.1 General specifications
One octave marked
*
indicates a change from the lnltlal frequency to double or half frequency.
For example, any of the changes from lOHz to 20Hz, from 20Hz to 40Hz, from 40Hz to 20Hz,
and 20Hz to 10Hz are referred to as one octave.
