Abstract

　少なくとも携帯電話機能、ネットワーク通信機能及び、地上波ディジタルテレビ放送受信機能を搭載した多機能の携帯通信端末において、特別な付加回路部品の追加等なく、地上波ディジタルテレビ放送受信機能の動作確認の自己診断がどこでも良好に行なえるようにする。 　ＤＴＶ受信装置４の動作確認の自己診断時、ＧＳＭ送受信回路２及びＷＬＡＮ通信装置３の送信出力を利用し、ＧＳＭ送受信回路２の第１の送信信号とＷＬＡＮ通信装置３の第２の送信信号とを、ＤＴＶ受信装置４のＬＮＡ４１の非線形特性によって混合し、この混合によってＤＴＶ受信装置４の受信周波数帯の両送信信号の差の周波数の差信号を生成し、この差信号によってＤＴＶ受信装置４の動作確認の自己診断を行なう。
