Talk:Zero crossing threshold detector

This detector exploits the property that the instantaneous frequency of an FM wave is approximately given by f = 1/(2*delta t)where Δt is the time difference between adjacent zero crossings of FM wave

Why are the Vsat voltages different? —Preceding unsigned comment added by 131.251.143.248 (talk) 13:15, 15 March 2011 (UTC)

Reverted redirect

 * I reverted the redirect of this article to Operational amplifier applications, because too much information was omitted in the merge, including the references section and applications section of this article. At the very least, the omitted information should have been merged to the talk page of the Operational amplifier applications article. See WP:PRESERVE for more information.
