Summary
[edit]
| Description |
English: Typical pattern of amplitude distortion of a LED-LDR optoisolator (vactrol) as a function of RMS AC voltage across the LDR (photoresistor). In the absence of DC bias, most of distortion is third harmonic, with some second harmonic. At very low voltages, distortion levels at a residual floor and is (somewhat counteintuitively) almost all second harmonic.
