Automatically adjusts the gain, or amplification, of a signal.

Use the AGC VI to control automatic scaling of a signal.

Details  

	AGC input is the signal for which you want to perform automatic gain control.
	filter value specifies the weighting factor that determines the smoothness of the frame-to-frame transitions.
	average amplitude specifies the average amplitude for the automatic gain control.
	minimum threshold indicates the minimum level at which to perform automatic gain control. If the signal is below the value of minimum threshold, automatic gain control is not performed. Values below minimum threshold are usually noise.
	AGC output is the signal with automatic gain control.

AGC Details

The AGC VI attempts to normalize an input signal level using the values of the input parameters. The filter value implementation is an exponential filter with the following:

AGC Value = Filter Value * AGC Value + (1- Filter Value) * Last AGC Value
