1.1 Definitions
Consider two sinusoidal signals of the same pulsation ω :
and
ϕ is, by definition, the phase advance of e 2 (t ) over e 1 (t ), measured by the distance between two maxima or two zero crossings.
This definition assumes that the signals are pure; this is rarely encountered in practice. In fact, a pure sinusoidal signal e 1 (t ) applied, for example, to the input of a linear system generally gives, at the output of the latter, a signal e 2 (t ) which...
