Change the subject when tou can't do anything else. >Typical loser attack. Eeyore was essentially history, then along comes the dorko twins to feed the troll. That's OK. Since my filter scheme relies on a "key" file rather than having to change the program, I see all kinds of possibilities for even better troll/troll-feeder filtering ;-) ...Jim Thompson -- | James E.Thompson, CTO | mens | | Analog Innovations, Inc. | et | | Analog/Mixed-Signal ASIC's and Discrete Systems | manus | | Phoenix, Arizona 85048 Skype: Contacts Only | | | Voice:(480)460-2350 Fax: Available upon request | Brass Rat | | E-mail Icon at http://www.analog-innovations.com | 1962 | Help save the environment!

Hmm, can't you just AC couple them into the opamp? ** Yep - as I have already said, there will be an improved s/n ratio as a result. When several similar mic capsules are paralled - the random noise voltage drops, compared to one. However, the signal output will remain essentially the same (as from one) long as the capsules are sited together in a directional array. This simple fact has got some here bamboozled. ...... Phil

That would be a 'black ho', wouldn't it? -- Offworld checks no longer accepted! |
