Say I have a 12V pwm that provides two duty cycles to control the intensity of a lamp; bright and dim. But lets i want to change this behaviour but I am unable to affect the control system upstream of this.
I want the bulb to be on only with the higher intensity but be off when the lower intensity duty. What would he best method for doing this? Could I use a basic high pas filter?
Current conditions
Large duty = bright
Low duty = dim
New conditions
Large duty = bright
Low duty = off
