single-sided power spectral density
This'll hold if the signal at "+f" and "-f" are uncorrelated. But since the signals at "-f" and "+f" are just a represntation of the actual signal at "f" they must be correlated and thus we must add the signals to get four times the power (and not the powers...
Hi
Please explain how the functioning fails with single supply. Do trace whther the output is unexpected at the o/p of tone control or amp.
The only plausible reason for this could be that you are having interference in tone control from amplifier.
You can do following:
1) Try makng a...
double sided power spectral density
Hi Janath
I am talking about the frequqency representation of noise itself. A noise at frequency "f" can be written in terms of phasors at "+f" and "-f" and they will be correlated (because we started with a noise and decomposed it in representation). So...
Re: pll
As far as the cycle slip is mentiond in the paper, I think there can not be any more explanantion of the phenomenon.
It's just PFD dependent phenomenon. Choose your PFD and you may or may not get this phenomenon.
As I asked - What do you need this for - do you need any more info...
Hi
What exactly you mean by level-detector?
The problem in using capacitive divider (as far as I know) are:
1) You can divide only decently high frequency signals
2) You will need to provide the bias for the output of this divider.
3) Leakages can be disastrous.
Hi aryajur
Just curious why you want to do this?
Anyway, are you referring to the point that since the anode and cathode are pretty much parallel in normal batteries (using concentric shells) so there will only be slight fringe electric field outside the battery and rest inside the battery...
two sided psd
Yes it is mentioned so in the books but I thought this must be 4 and not 2 because :
1) The sinusoid of frequency "f" is a sum of phasors at "+f" and "-f "
2) They will be correlated for the case of noise(actually its just f in real world and it's represented as "f" snd "-f"...
two-sided power spectral density
Hi
The ratio of single and double sided spectrum is mentioned equal to 2 in books.
But according to me it must be 4 because if you convert DS-PSD (double sided PSD) to SS-PSD you fold the negative frequencies to the positive ones and they must be correlated...
Re: USB compliance test
Hi Iouri
Yes, I've seen usb.org but still it is not clear whether it is the cycle-cycle jitter or the phase jitter that'll close the eye. I'll post this question on their forum also.
On first thought it seems that phase jitter will be considere in the eye opening...
Re: About pss and jitter
Hi
The paper is present at

Did you have anything to discuss in the paper?
simulate amplifier offset voltage
Hi
I think that measuring the systematic offset at any convenient input bias won't be helpful - Systematic offset changes with the bias voltages in the situation your op-amp is put into. So, better will be to simulate the op-amp with its actuial stimulus and...
