Hey All,
I've got a design that will output a pulse every N clock cycles, where N is specified by an A/D converter. As such, the frequency of the pulse generating VCO is defined as Fclock/N. Does anyone know a relatively temperature stable way to calculate N = 2^(-x)? As a programmer, because I want my VCO to operate at 1 volt per octave, the obvious solution seems to be scaling my input - but I don't know if that assumption holds for physical hardware. I imagine this would take the form of some sort of exponentiator, but I do not know if hardware exponentiators will function with negative exponents.
Thanks in advance,
-Erich
