Hi!
My task is to write a review of available methods and techniques of measuring alternating voltage in the audio frequency range.
For several days looking for information on the internet, but can not find anything.
Unfortunately, the results of my research are, hmm... Everywhere is talking about alternating current rather than voltage. I learned so much that audio frequency has a range from 20 Hz to 20 kHz ... but the methods and techniques of measurements for it? Everywhere there are only some guides have any equipment. Or maybe a better idea would be to look for it in some books than in the Internet? Or maybe he met someone with the subject and knows exactly where to be found?
Thank you in advance for your help and best regards!
