I want to measure current for a small DC motor driven with a PWM signal. Working voltages are less than 2 volts and expected current is less than 1 amp. I have a M series 6233. I am using a shunt to measure my current and am feeding it into two analog inputs. I need to convert the PWM pulses into an analog wave to display on a graph. The net question is how do I convert PWM pulses into an analog wave form?

Thank you for your response.
I am using Labview. And I am reading in the voltage drop across my shunt. I do the math in Labview and convert the shunt voltage to current and display that result. This provides me with a wave form that follows the PWM voltage supplied to the motor. I need to have an analog signal as I have a few crossovers to evaluate between current and voltage.
