by using simulink,we can simulate the phase locked loops' dynamic performance, for example frequency step response. but how can i find the loop's equivalent noise bandwidth and damp coefficient?
A PLL is a feedbak system: You can sure use simulink to do Your work. But, I tell to You to use the NI LabView. It's optimized to work about commnucation systems. I've implemented in past a LV code who simulate a Costas' Loop. If You are interested in more details about LabView, send me a privete message.
