Fixed Point Numerical Systems for Digital Control

August 29, 2015 by Tim King

One question which is commonly asked is “how do I represent fractional numbers on my fixed-point MCU, DSP or FPGA?” One of the best solutions to this is use of the Q number system. The Q number system is a fixed point system where the available bits are divided amongst the integer bits (those to […]
