    • PURPOSE: A receiver with analog and digital gain control, and a respective method are provided to improve the performance of the receiver by excluding the use of digital gain control and using analog gain control of a receiver while decoding a communication channel. CONSTITUTION: A digital controller(MC) provides the digital gain control operations of first and second amplifiers(A1,A2), and a digital gain setting operation through the digital gain control operation after selecting a communication channel. The digital controller fixes the digital gain setting operation, and provides an analog gain setting operation through the analog gain control operation while decoding the communication channel.
    • 目的:提供具有模拟和数字增益控制的接收机以及相应的方法,通过在解码通信信道时排除使用数字增益控制和使用接收机的模拟增益控制来提高接收机的性能。 构成:选择通信信道之后,数字控制器(MC)提供第一和第二放大器(A1,A2)的数字增益控制操作和通过数字增益控制操作的数字增益设置操作。 数字控制器固定数字增益设置操作,并且在解码通信信道时通过模拟增益控制操作提供模拟增益设置操作。
