ABSTRACT:
A digital radio receiving apparatus includes a transversal demodulator which is controlled under an internal control mode and an external control mode selectively by means of a control circuit. The control circuit operates under the external control mode every time an alarm signal is issued when the transversal modulator functions in an abnormal operation state due to fading. In the external control mode, the control circuit produces an optimum control signal for elimination of the alarm signal.
