Counter fundamentals
- [Instructor] In addition to general purpose digital I/O lines, many DAQ devices include another type of specialized digital hardware called a counter, which can be used to measure and generate sequences of digital pulses. Counters operate on digital signals which are represented as one of two possible voltage levels. They can be used to count the number of pulses, by counting the number of rising edges or falling edges. And they can measure other characteristics of the digital signal, like the frequency of pulses, the pulse period, pulse width, duty cycle, and even the difference in time, between rising and falling edges of two different input signals. In addition to measuring these type of signal characteristics, counters are commonly used to capture the signal from digital encoders. An encoder is a device that's used to measure linear or angular position. A common example of an encoder would be a digital knob…
