Fig. 6. Prediction of 40-Hz auditory steady state response (ASSR) using selected portions of the 5-Hz transient grand average waveform. (  A ) Five-Hz grand averaged transient from  figure 4 with peak labels tentatively assigned and (  B ) predicted (  dashed )and recorded (  solid )40-Hz ASSR. The whole 5-Hz transient waveform and portions thereof (labeled  a –  d )were convolved to generate predicted waveforms. (  C ) Phasor diagrams showing the corresponding and similarly labeled predicted (  solid ,  bold ) and recorded (  dashed ) vectors. Avg = grand average.
