Understanding Impedances - MIT OpenCourseWare

Another important (and confusing) thing about impedance is that it needs to be described as a complex number with both real and imaginary (i = √ −. 1) parts. To simplify things, instead we state impedance as a . magnitude |Z| (the overall amount of impedance) and . phase angle Z. Remember how the woofers in the open baffle made almost ................
