Problem with simulateDSM for nlev > 3 #65

Closed sinkra closed 6 years ago

sinkra commented 6 years ago

It looks simulateDSM operates correctly for nlev=2 and nlev=3 but not for nlev > 3: for even nlev it gives same results as for nlev=2 and for odd nlev it gives same results as for nlev=3.

Matlab delsig toolbox shows the same same behaviour. That is because simulateDSM was tested with the same input sin wave amplitude=1 while the DSM model input range is increased with the quantizer nlev.
