ABSTRACT:
The automatic gain control loop has an automatic gain control loop filter generating a multi-bit gain control word in response to the power level of the output signal of the loop. A shifter circuit shifts the input data by selected number of bits under the control of selected most significant bits of the gain control word multiplying the power of the input signal. A multiplier circuit multiplies the shifted data output from the shifter circuit by predetermined multiplication factors under the control of the remaining bits of the gain control word. The shifting and adding of the input data under the control of the gain control word maintains the power level of the output signal within a predetermined range.
