HowdyA more complete comparison would help.
Show what a bandlimited signal looks like with just quantization and no dither, filtered and unfiltered. Then show the same with dither both filtered and unfiltered.
It's also interesting to do this with a low freq signal and compare it to a high freq signal (say 1/4 to just under 1/2 fs)
If your input signal isn't bandlimited, it will surely not look at all like a sawtooth after sampling! (Aliasing and all...)
