This article shows that not all frequency meters need to be complex and expensive. With the aid of some standard logic it is possihle to determine the frequenq of digital signals. The counter makes use of two 3-digit BCD counters that have a multiplexed output with buffer memory and a reset input. The multiplexed output signal is converted by an integrated BCD-to-7-segment converter and then applied to an LED display.
