Abstract

PURPOSE:To improve the aural sensitivity by providing a circuit which can eliminate the signals near at least 4.5MHz between the final step of the wide-band amplifier and the aural intermediate frequency wave detector. CONSTITUTION:HPF10 is connected between video intermediate frequency amplifier 2, i.e., a wide-band amplifier and aural intermediate frequency wave detector 4. The aural noise is reduced during the weak electric field since HPF10 can eliminate the signals near 4.5MHz. Thus the aural sensitivity can be improved.
