Thanks a lot for the hint !

Hi,
very interesting test
Nevertheless even if my experience with batteries is very limited i would choose them any time.
I suspect the 220uF capacitor to buffer the battery output was too little.
I would use a very high quality (low ESR) and high capacity (at least 10000uF) capacitor to buffer the output
Then i would like to see the noise spectrum a lot
Thanks again
Kind regards,
bg

Good to konw and cuts through the 'battery' fantasy of 'perfect power supply' rather well. nt - Elizabeth 15:17:28 04/12/14 (0)
