    • In a wireless receiver apparatus including a gain control amplifier for controlling a gain of a reception signal, a maintaining device compulsorily maintains the gain of the gain control amplifier at a predetermined fixed value only in a predetermined specified interval. The maintaining device includes a latch circuit for maintaining a gain set value immediately prior to the specified interval. A start timing of the specified interval is determined by an edge of a predetermined timer start signal, and a duration of the specified interval is determined on the basis of a count of a predetermined timer clock signal and a count of a predetermined timer count set bus signal.
    • 在包括用于控制接收信号的增益的增益控制放大器的无线接收机装置中,保持装置仅在预定的指定间隔内强制地将增益控制放大器的增益保持在预定的固定值。 保持装置包括用于在紧接指定间隔之前维持增益设定值的锁存电路。 指定间隔的开始定时由预定定时器启动信号的边缘确定,并且基于预定定时器时钟信号的计数和预定定时器计数总线的计数来确定指定间隔的持续时间 信号。
