Electronic tuner?

Hi. Are the "electronic tuners" used by musicians to tune instruments (like this one) examples of frequency counters, or are these tuners a different thing? Thanks. --Allen 01:08, 14 March 2006 (UTC)[reply]

They work on a different principle, in that internally they generate a set of reference tones corresponding to the tuned note, and mix this with the incoming signal in a quadrature detector. The output of this is a DC signal that corresponds to the frequency difference between the input and the ref tone, and is used to drive the meter. It's a lot simpler doing it this way than trying to actually count the incoming frequency, especially as musical instruments generate a lot of harmonics and simply counting might not work very well anyway.

Thanks! I'll make a separate stub for these music tuners, then. --Allen 03:50, 14 March 2006 (UTC)[reply]

Use information

It would be good to have a paragraph or two outlining the potential use cases of frequency counters. With examples. In fact that is why I came to read this article in the first place after seeing devices advertised (with no explanation) in radio magazines. 125.239.135.26 (talk) 22:06, 17 February 2024 (UTC)[reply]
