In the LM311 circuit below that is used as a comparator, how does voltage at the reference (- Input), affect the output?
For a sine wave, would having a higher voltage at the reference increase or decrease the duty cycle of the output?
And finally, is there a way to calculate this duty cycle, based on the resistor values of the voltage divider at the reference input?
NOTE: The circuit above is just for reference. The application I am using an LM311 for is something else.
