20-5 フィルタの帯域内偏差が地上デジタル放送信号に与える影響(第20部門 放送技術(無線・光伝送3))

抄録

In terrestrial broadcasting relay stations, various filters are used for mitigating effect due to other channel signals. However, the actual filters have amplitude ripples in the passband and deteriorate the quality of broadcasting signals. In this satiation, we measured how input and output filters affect the terrestrial broadcasting signals.
