Quadrature signals are based on the notion of complex numbers and perhaps no other topic causes more heartache for newcomers to DSP than these numbers and their strange terminology of j-operator, complex, imaginary, real
, and orthogonal. If you re a little unsure of the physical meaning of complex numbers and the j -1 operator, don t feel bad because you re in good company. Why even Karl Gauss, one the world s greatest mathematicians, called the j-operator the shadow of shadows . Here we ll shine some light on that shadow so you ll never have to call the Quadrature Signal Psychic Hotline for help.
