Feedforward automatic gain correction |
摘要 |
<p>An automatic gain control circuit is provided for an input signal in the form of a dc reference level and a superposed amplitude modulated ac data signal. A feedforward AGC loop has a low pass filter (41) for deriving the level of attenuation from the attenuated dc reference level. A multiplier value (G) is based on the reciprocal of the level of attenuation (±) and this multiplier enables an output signal to be generated comprising a constant multiple (DG) of the input signal.</p> |
