Circuit for detection of AC under and over voltage

[Vicent Yang]

Dear all :
does any one have a guide of how to build a circuit to detect AC voltage. This circuit will be used as under and over voltage detector for the AC voltage.

Please try this link and read about the CS5460 and this project: **broken link removed**.
I am working in a similar project on detecting the half period 60 Hz Sine wave.
Good luck...
