occheung 389b97d9e4 5108: make ADC-Repeaters-EEM path unidirectional 
The only signal that enters the ADC through the repeaters is the SPI clock.
It is only a state/time reference, no meaning info goes through this path.

occheung 5c962c64d4 5432: ditch import statement in python 
Obviously, the import statements cannot be put right before the methods in the same indentation.
It was there because there wasn't a better way to put these code.
Now, it is replaced with an worded instruction that imports are needed.

occheung ac8d398f5e suservo: refrain from generating channel list 
For consistency with other DDS examples that uses multiple channels.
e.g. TTL relay external trigger, DDS synchronization

occheung ce563bdcf1 4410-4412: remove fractions & literal word symbols 
Some of them are added in 05eba6fa.
Very certain the fraction symbols are rarely used in any other datasheets to express decibels, if any at all.

occheung 7841162bd6 5432: remove symbols 
revert b9ce64ed.
The remaining symbols are very standard (e.g. V, Z), so the symbol column is removed instead.

occheung 2613df692b 4410-4412: fix dds signal spec citation 
* cite wiki instead of datasheets for frequency range, as the rest of the signal chain has low response for low frequency
* cite wiki instead of ad9912 datasheet for frequency resolution, see the ad9912 design bug on wiki

occheung 022563a056 5432: uncite IC for output voltage spec 
There are other elements on the output signal chain, like the unity op-amp folowing the DAC.

occheung 14776cf74d 5432: revert url footnote 
Auto-recognizing footnote as url is really a browser feature.
Chromium will not be able to parse the underscore in Zotino DAC IC datasheet URL.
