[time-nuts] DDS'ery

[Luis Cupido]

Folks, a quick one...

A DDS, that is an accumulator with a DAC followed by a low pass filter 
and comparator (zero crossing) to produce a square wave to drive a PLL 
or a MIXER or else (at logic levels).

Isn't it the very same thing as just using the most significant bit of 
the accumulator.

Or am I missing something here ?

Comments appreciated.
thanks.
