Abstract

PURPOSE:To make constant the width of fluctuation of detected output, by changing the response time constant of the center value detection circuit according to the speed variation of irregular variation signal. CONSTITUTION:In a mobile radio, the mobile speed v and the fading pitch have a correlativity. The comparator 2 compares the input signal with the output of the integrator 3, i.e., the output of the center value detection circuit, and it outputs -E or +E depending on the magnitude. The variable attenuator 5 varies the attenuation inversely proportional to the control signal 9. The control signal gives a voltage in which the attenuation is greater with slower mobile speed v. Accordingly, since the gain is in proportional to fading even with the integrator 3 constant, the output variation width 11 can be constant.
