Got a couple of questions here guys
I have a unit circle with just 1 pole and a lot of zeros. What condition could result to this and does it have any effect on the dsp system
Why do poles appear as real/complex conjugate pairs.
Thanks

to have more zeros than poles require that the system is not causal. something that can exist in theory (and we do that with non-realtime DSP processing which can look ahead to "future" samples when it computes and outputs the "present" sample) but not in practice (those "future" samples referred to were really recorded long ago and saved in a file or buffer). perhaps you might think there are more zeros than poles but that might be because there are poles located at $z=0$ that you're not counting. FIR filters have all of their poles at the origin.
