Good morning,all
The input of amplifier is the output signal of the chip AD2S1205 , (this is the AD2S1205's datasheet: http://www.kynix.com/uploadfiles/pdf/AD2S1205WSTZ.pdf ) Vref_ADI also is the output reference voltage of decoding chip.The output signal of amplifier is the drive signal of rotating transformer. I found that the outputted drive signal has a distortion which is non-periodic.The schematic diagram and the voltage wave is as following.Could you help me?
The two pass is input signal “Exc+_Sig to Exc-_Sig” and the four pass is “EXC+to EXC-”.
