The extension of horizontal luminance bandwidth is one of the subjects of the second generation EDTV, so far, some proposals have been made, which fold down horizontal high component into 4.2MHz band by modulation of subcarrier. Using the transmission model we have proposed before, step responses of horizontally extended bandwidth signals are compared varing the subcarrier frequency, subcarrier phase error in demodulator, and so on.
