Notes/Equations
  1. This quantizer model outputs a delayed, uniformly quantized representation of the baseband portion of the input voltage. The input impedance is infinite. The delay is fixed at one timestep. The quantization state output mode is in offset binary format.
    The input quantization level is equal to Δ = ( Vmax - Vmin ) / ( N - 1). Any input less than ( Vmin + Δ /2) is assigned to state 0. Any input greater than ( Vmax - Δ /2) has a state equal to ( N - 1). If the OutState parameter is true, this quantization state is directly output. If the OutState parameter is equal to zero, the quantization state is scaled and offset, Vout = Q/Δ + Vmin , to match the input voltage.
  2. This model works in transient and circuit envelope simulation.
  3. An example of using this component along with SampleHoldSML follows.
