Hi all, Again, maybe playing th unpaid professor a bit too much (but that IMO is better than the opposite), remember the relevant theories when dealing with ANY dsp subject: *) The real signal is only known at the sample times (assuming correctly sampled data) and to get information about

[music-dsp] convolution in the frequency domain

2011-02-20 Thread Thomas Rehaag
Hi, I'm trying to create an aliasing free multiplication of two signals. As far as I remember from my days at the university (long time gone) a multiplication in the time domain can be replaced by / is the same as a convolution in the frequency domain. And the convolution can help to avoid
