    摘要： In an audio muting circuit, after a short delay from a first time at which a first mute signal generation circuit causes a first mute signal to fall from “H” level to “L” level, a second mute signal generation circuit causes a second mute signal to fall from “H” level to “L” level at a second time. A third mute signal generated by combining the first and second mute signals is caused to fall from “H” level to a predetermined level at the first time, and caused to fall from the predetermined level to “L” level at the second time. Thus, at the start of muting, the level of an audio signal is increased in stepwise manner. In this way, noise generated at the start of muting can be reduced.

    摘要翻译： 在音频静噪电路中，在从第一静音信号产生电路使第一静音信号从“H”电平降低到“L”电平的第一时间之后的短暂延迟之后，第二静音信号产生电路产生第二静音 信号第二次从“H”电平降低到“L”电平。 通过组合第一静音信号和第二静音信号而产生的第三静音信号在第一时间从“H”电平下降到预定电平，并在第二时间从预定电平下降到“L”电平。 因此，在静音开始时，音频信号的电平以逐步的方式增加。 以这种方式，可以减少在静音开始时产生的噪声。

    摘要： The present invention relates to a mobile communication system in which data is transmitted and received through a wireless transmission line between a mobile station device and a network-side device. A receiving-side device includes a retransmission request transmitter configured to transmit, to a transmitting-side device, a retransmission request for requesting retransmission processing on each data unit of the data, when a reception error is detected in the data unit. The transmitting-side device includes a retransmission time storage configured to store a retransmission time at which the retransmission processing is performed on the data unit; and a retransmission controller configured to control so as not to perform the retransmission processing on the data unit related to a received retransmission request, when the retransmission time of the data unit is stored and a difference between the retransmission time and a current time is shorter than a retransmission prohibition period.
