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
 2022-01-20 16:48:58 +08:00
occheung 8404fed3da 4410-4412: get example code from file 
Updates #24. Added example files for DDS and SUServo respectively.

occheung 73714d0028 4410-4412: remove symbol column except for test characteristics 2022-01-19 12:39:24 +08:00
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.
 2022-01-19 12:29:42 +08:00
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
 2022-01-18 17:05:31 +08:00
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.
