Frequency counters are digital indicating meters for accurate measurement and display of square wave and pulse input signals. There are several types of frequency counters which differ in frequency ranges and the number of digits that can be displayed. A digital counter represents the count in digital form. A frequency counter is an electronic instrument used to measure frequency and time. Digi... (read more)
