| Voltage = distance in cm × volts/cm
Example: peak-peak voltage = 4.2cm × 2V/cm = 8.4V amplitude (peak voltage) = ½ × peak-peak voltage = 4.2V Time = distance in cm × time/cm Example: time period = 4.0cm × 5ms/cm = 20ms and frequency = 1/time period = 1/20ms = 50Hz Can your please give me examples from these formulas i need please 1.) Pulse width Modulation PWM? Pulse widith Modulation= distance in cm X time/cm? example? 2.) Duty Cycle? Duty Cycle = distance in cm X time/cm? example? 3.) Pulse width? Pulse width = distance in cm X time/cm? example? 4.) Time constant? Time constant= distance in cm X time/cm? example? 5.) Rise time and Fall time? Rise time= distance in cm X time/cm? example? Fall time= distance in cm X time/cm? example? |

| How do i measure Pulse width Modulation (PWM) ?
with a oscilloscope? How do i measure the Duty Cycle of the PWM? with a oscilloscope? How do i measure the Pulse width? with a oscilloscope? How do i measure the Time constant? with a oscilloscope? How do i measure the rise time and fall time? with a oscilloscope? how to Measure the Period and frequency of the PWM? with a oscilloscope? |
