Good Morning! I am new to digital signal processing, And I am currently working with DSPIC33F. I used Matlab design Filter to extract the coefficients of the filter. My Problem is within my Data because it is written in 20 bits. I wonder if this will work correctly or I need to change the microcontroller. Regards!

  • $\begingroup$ I've done real-time DSP with the Motorola MC6809 and the MC68000 which were 8-bit and 16-bit integer CPUs. If you're careful with coefficient scaling and your filters aren't extremely resonant, you can get away with 20-bit. $\endgroup$ – robert bristow-johnson May 15 at 18:17
