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 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 8f1a437378 4410: add ram modulation with synchronization example 2021-12-07 16:26:25 +08:00
occheung 011d63f3eb 4410: modify ram example 
* Use `prepare()` to init the arrays, would be great if the value can be prepared there. However, the type check was not happy about it.
* Separate RAM configuration into a separate function
* Separate DDS init, digital attenuation & switch config in an init function
* Use `dds.set()`. It is supposed to look simple.

All these are to avoid repeating the long code in the coming RAM+SYNC example.

occheung 0dbf7a70c4 4410: add phase param to single-tone sync e.g.

occheung b657e0fea5 4410-4412: clarify nominal power 
The same figure can be found in sinara issue 354 / urukul issue 3, and it was meant to be an empirical limit for low frequency RF outputs.
