Vhigh

Upper threshold voltage

V

0.75

Notes/Equations
  1. Comparator outputs a 1V signal whenever the baseband portion of the input signal is between the two threshold voltages. Input impedance is infinite; output impedance is fixed at 0.1 Ohm; and, there is a fixed delay of one timestep.
  2. If the baseband portion of Vin is greater than Vlow and less than Vhigh, then the output voltage at the next time sample is 1.0V; otherwise, the output is 0.0V.
  3. This model works in transient and circuit envelope simulation.
