Title: create finite delay of PFD in simulink
Post by casual on Dec 15^th, 2009, 6:57pm

I try to model finite delay (nonideality) of PFD in simulink. I use the delay transport element. But it gives me weird output waveform because it ramping up and dn (poor slew rate) instead of giving me delay that I set (I set to 20% of the period). The input of the delay transport is a ideal squarewave pulses.
Hope someone can advise me.

I think that cppsim is a better choice for simulation so in detail, cppsim is especial convenient for PLL simulation because it contains lots of example blocks.
