General question :
A DAC can give out a glitch at major code change.
one option to 'minimize' this on the output is to use a R/C low pass filter.
Debate raging here, does the filter 'remove' the glitch , or smear it over time ?
One side here says the glitch is attenuated,
effectively the glitch is dissipated as 'heat' in the capacitor.
One side says the glitch is attenuated ,
the impedance of the DAC output forms a frequency dependent voltage divider,
One side here says the glitch is attenuated,
but the energy before and after the filter is the same, its just spread out in time,
Anyone got any thoughts that I can hook together ,
