Hi Vinnie;

Sure, its done all the time.

For low frequencies the input signal (or several input cycles) is the "gate" for counting a clock, and that is inversed by a division to get frequency.

For high frequencies the input cycles are counted for a specified period of time (the "gate"), and then (probably) scaled to get the range right.

Cheers,

Peter (pjv)
