Hi, all, Does anybody know how to do phase shift in Simulink, e.g shift a single with 90o ? Thanks, |

You want a Hilbert Transformer filter, which you can design with the
Digital Filter Design block if you have the DSP Blockset. Under Filter Type, set the list box that says "Differentiator" to "Hilbert Transformer". You also need to to specify the bandwidth of your signal, since it's not possible to phase-shift ALL frequencies by 90 deg at the same time, and choose a filter order that is sufficient to actually achieve that bandwidth without too much magnitude-response distortion. > -----Original Message----- > From: jzzhu4 [mailto:] > Sent: Wed, April 03, 2002 11:05 PM > To: > Subject: [matlab] phase shift > Hi, all, > Does anybody know how to do phase shift in Simulink, e.g shift a > single with 90o ? > Thanks, > > ------------------------ Yahoo!
