I have an application where I have 2 supply sources vary in range of 300mV-800mV.
I need a circuit that can take these 2 signals and output the average voltage of both. Can it be done fairly simply?

I have an IC the produces a signal / code at TTL levels that I would like to
convert to a Line out signal so that I can record the codes on my computer.
Then I'd like to play these codes, take them from the line out from my

like to be able to both latch data and switch the outputs from high
impedance to low impedance, without risk of any 'junk' dat appearing on

I have a good quality car amp which i'd like to use to drive a home
sub. If i was to power it off the 12V rail of a 400W computer PSU
(with a big cap inline) it may run well. But i'm concerned that the
peak current draw will be more than the PSU can cope with.

Anybody know where I can pick up a couple of these?
I tried a replacement but it doesn't work :-(

I have an audio PA which rated at 4ohms 22W in bridge tied load or
2ohms in stereo mode. What will possibly happen to the audio PA when I
connects a 3.2ohms speaker parallel with 16ohms speaker in bridge
configuration?
