The Perfect Divider

May 24, 2011 9:41 am | by M. Simon | Blogs | Comments

Voltage dividers that divide by 10, or 100, or 1,000 are tough with standard resistors. The numbers do not come out exactly with standard resistors. By adding one resistor to the divider it is possible to get the division ratio exact (not counting resistor tolerances).

In my last post I discussed Forth as a language. A language that is based on a virtual machine. What if that virtual machine was turned into a real machine? Good things. For one operations can be done in parallel. Returns can be automatically initiated at the end of an instruction cycle.
