DEFINITION

Classification: 708/836

Time division:

(under subclass 835) Subject matter wherein one input variable is used to control the mark-to-space ratio and the other variable is used to control the amplitude of a repetitive rectangular wave.

(1) Note. Each variable can be represented by current or voltage and the output voltage, proportional to the area of the pulse voltage-time curve, represents the product of the input variables.
