发明名称 Switchable receiver with reduced amount of audible distortions
摘要 A receiver and a method for receiving a digital signal and an analogue signal is described, whereby both signals transmit the same audio program. In dependence of the reception situation, the receiver switches or slides from said digital signal to said analogue signal and back. Each time the receiver switches between the digital signal, which has an audio bandwidth of about 12 kHz, and the analogue signal, which has an audio bandwidth of only 4.5 kHz, the sound of the received audio output signal changes from a rich sound to a rather flat sound, or vice versa. To avoid this, the audio bandwidth of the digital signal is reduced in dependence of the reception situation. In case of frequent occurrence of switching, or in case of a bad reception of the digital signal, the bandwidth of the digital signal is reduced.
