Abstract :
The various methods of extending the range of frequency counters are discussed and some of the shortcomings of each are pointed out. A new method that minimizes these short-comings is in the range of frequencies that can be counted entirely by the frequency limitations of AND gates; also it requires no tuning and its counting precision is the same as that of the basic counter.
