Phase-versus-time analysis of the steady-state evoked potential latency.
Steady-state EP (evoked potenial) latency can be derived either from a phase or time difference between stimulus and EP. Phase derivation employs a sinusoidal stimulus and assumes a linear stimulus-EP system. Time derivation employs any stimulus waveform and does not require linearity. The two methods are complementary in application.
