... In this case, Vtotal = 5V and Rtotal = 10K. If you work out the math, the voltage across the 1KΩ resistor is 0.5V, the voltage across each 2KΩ resistor is 1.0V and the voltage across the 3KΩ resistor is 1.5V. These voltage drops give us the various fixed voltages we need for the comparators. Notice ...
