Tips: Digital counter application in digital system
Counter is typical sequential logic circuit and also is the most used sequential logic devices in digital systems. Using a digital counter to count pulses or conduct fractional frequency can achieve measurement, calculation, timing control and other functions. In addition to the counting function, the counter also has functions such as asynchronous reset, preset parameter, and hold. The preset function is divided into two kinds: synchronous preset and asynchronous preset. The former is controlled by timing pulses, and the later is not controlled by timing pulses. The hold function is also divided into two types: hold-carry and hold without carry. The counter can also be used as a sequential pulse generator.

In this video, ATO will show you how to wire a digital counter. And how to set the basic parameters of digital counter.
