Frequency response method

Frequency response method. Given: G ( j ? ) as a function of ? is called the freq. resp. For each ? , G ( j? ) = x ( ? ) + jy ( ? ) is a point in the complex plane As ? varies from 0 to ?, G ( j? ) = x ( ? ) + jy ( ? ) defines a curve in the x-y plane or the s=x+jy complex plane.
