#141180 - Why add complexity? Responding to: ???'s previous message |
Chico says he is waiting 25milliseconds before swithing channel.
That is many scores over 3.5microseconds calculated by KAI. Therefore I think this is unnecessary complexity. After adding buffers you have to check for their offsets. I found about 3-6mV offsets of different polarity of buffers. To check offset you have to be sure of signal being zero. As the Guru Don Lancaster says keep the things "simply elegant" ! No offense meant. purushottam |
