30 Jun 2010 Description: This example demonstrates how to measure a finite number of pulse widths on a Counter Input Channel. The Minimum Value i want to measurement pulse width (duration) of sound wave (get from ultrasonic sensor C:\Program Files\National Instruments\LabVIEW To learn how to use LabVIEW to count pulses and measurme frequencies using . Set the Gate Width to 1, and measure the frequency from function generator. Digital Read Pulse Width. Read a digital pulse width. Use the Stimulus input to specify a pulse type to send before measuring the response pulse. 7 May 2014 The formula for period, semi-period, pulse width, and two-edge separation is as follows: Period, Semi-Period, Pulse Width, or Two-Edge Separation (in seconds) = Count / Counter Timebase Rate (in Hz). You also can measure pulse and time using the Pulse Measurements VI and the Waveform Measurements VIs. The lab will configure a counter to read encoder pulses to measure shaft rotation . Concept 3: Generate a pulse-width modulated (PWM) signal with a timer and Acquisition Hardware. LabVIEW Data Acquisition Hardware Support . .. Nonreferenced Single-Ended Measurement System. Measuring a Pulse Width. and falling edges are the rise/fall time and the minimum pulse width. There are five different types of counter measurements—edge counting, pulse generation Accepts a periodic waveform or an array of periodic waveforms and returns the period, pulse duration (pulse width), duty cycle (duty factor), and pulse center of a
