The signal as shown in Fig.
Referring to Fig.
When assuming;
1)the signal passing through DAC1 ® Q502 ® Normal amp. 1 ® SW31 ® SW5 ® Q516 to the positive phase 1,
2)the signal passing through DAC1 ® Q502 ® inverted amp. 1 ® SW32 ® SW5 ® Q516 to the inverted phase 1,
<1st frame>
3)the signal passing through DAC2 ® Q504 ® Normal amp. 1 ® SW41 ® SW6 ® Q517 to the positive phase 2 and
4)the signal passing through DAC2 ® Q504 ® inverted amp. 2 ® SW42 ® SW6 ® Q517 to inverted phase 2,
the AC and DC levels of the positive phases 1, 2 and the inverted phases 1, 2 are expected to be the same.
However, each voltage will vary slightly owing to the adjustment variation. In this case, each frame signal is assumed as follows.
