Saw this little module on EEvblog. I suspect not up to the standards for Time Nuts <g> but nonetheless interesting. Needs to be translated from Spanish to English.
This is an experimental module that developed as a concept for frequency measurement applications . The synchronous converts a periodic signal with amplitude and random manner in a square wave signal with the same frequency . The module input accepts analog signals with voltage up to 53Vrms . The output of the CMOS type , can be connected directly to a digital circuit (for example, an input of a micro-controller ) . Thus, it is possible to measure the frequency of the original signal by counting the number of rising or falling flanks in the module output signal.
