hi, I've never taken an official course in electronics, so some of these questions may seem a little obvious. But don't think I'll be insulted if you say stuff that you think is obvious in your replies. It willprobably be helpful. Thanks. So, I need to 'deamplify' a TTL signal so that the output of this 'deamplifying' circuit has a lower voltage (~10 milivolts). As far as I know, the only way to reduce the voltage is to use a transformer. Is this true or is there another way? Are there any transformers that introduce very very little noise? I need a minimum of noise in the deaplification. Is deamplification the right terminology?
