WebThe poles and zeros can be either real or complex numbers. However, since the a and b coefficients are real numbers, the complex poles (or zeros) must occur in conjugate pairs. That is, if 5+j3 is a zero, then 5 – j3 also must be a zero. A zero that is purely imaginary (±jωZ) causes the transfer function T(jω) to be exactly zero at ω =ωZ ... WebWe know that a polynomial of degree #n# has #n# zeros (counting multiplicity). So a polynomial of odd degree has an odd number of zeros. We also know that if a polynomial has real coefficients, the any imaginary zeros occur in conjugate pairs. So we can … #Delta > 0# indicates that the quadratic has two distinct real zeros. #Delta = 0# …
