simulink discrete-time integrator problem
Hi,
I want to simulate a DS modulator in simulink. When I use,
Input frequency = 85/8192
Sample time = 1
like the values in the Schreier toolbox, everything is ok. But when I use,
Input frequency = 85
Sample time = 1/8192
The modulator does not work. I guess the problem is something to do with the simulink and the blocks, which may ignore or round the numbers when they are so small. I set the sample time for one block and for other blocks I set -1 for inherited.
Any suggestions?
