So what have you done?		01/01/70 00:00
Require more work...		01/01/70 00:00
Working on that		01/01/70 00:00
options, options		01/01/70 00:00
Help me		01/01/70 00:00
Okay		01/01/70 00:00
Are many threads available		01/01/70 00:00
when you save a char ...		01/01/70 00:00
Why don't you specify your problem COMPLETELY?		01/01/70 00:00
Already specify it		01/01/70 00:00
there are some details?		01/01/70 00:00
comparisions		01/01/70 00:00
How are you calculating your needed sample rate?		01/01/70 00:00
start with simple one....		01/01/70 00:00
You do know sin(90+angle)? Or 2-log computations?		01/01/70 00:00
ADC resolution............		01/01/70 00:00
impossible or wrong		01/01/70 00:00

Precision rectifier is suitable for any waveform		01/01/70 00:00
are u sure??		01/01/70 00:00
Depends		01/01/70 00:00
must be severely bandwidth limited		01/01/70 00:00
Maybe was circuit with top-voltage capacitor		01/01/70 00:00
Sorry for confusion		01/01/70 00:00
What accuracy do you need?		01/01/70 00:00
360/1024		01/01/70 00:00
Not what he (or me) have asked		01/01/70 00:00
you are right....		01/01/70 00:00
Do you believe you can protect your circuit from noise?		01/01/70 00:00

Some of those rules are showing their age		01/01/70 00:00
here we go again		01/01/70 00:00
think about this for a minute		01/01/70 00:00
when discussing a FAQ		01/01/70 00:00
Well, when were those cap sizes determined?		01/01/70 00:00
Technology		01/01/70 00:00
Steady state currents do not need decaps		01/01/70 00:00
Often low capacitance so limited charge. But remember load.		01/01/70 00:00
fixations		01/01/70 00:00
Nothing. has been proven yet.		01/01/70 00:00
