APPARATUS AND METHOD FOR IF SWITCHING IN A DUAL-TUNER, DUAL-IF HD RADIO AND FM/AM RADIO RECEIVER

摘要

In a dual-channel HD radio receiver (40), when the broadband filter (421) channel is compromised, the broadband channel is inactivated and the narrowband channel is activated. By mixing the signals of the two channels during the change, undesirable audio artifacts can be minimized.
