Patent ID: 8200731

Claim:
A device for determining a coherence measurement for a signal, comprising: a) a digitizer, having an input for receiving the signal, and having an output; b) a transformer, having an input connected to the output of the digitizer, and having an output; c) a first squarer, having an input connected to the output of the transformer, and having an output; d) a second squarer, having an input connected to the output of the digitizer, and having an output; e) an adder, having a first input connected to the output of the first squarer, having a second input connected to the output of the second squarer, and having an output; f) a subtractor, having a first input connected to the output of the first squarer, having a second input connected to the output of the second squarer, and having an output; g) a standard-deviation function block, having an input connected to the output of the subtractor, and having an output; h) a mean generator, having an input connected to the output of the adder, and having an output; i) a first multiplier, having an input connected to the output of the standard-deviation function block, and having an output; j) a divider, having a first input connected to the output of the mean generator, having a second input connected to the output of the first multiplier, and having an output; and k) further including a second multiplier, having an input connected to the output of the divider, and having an output.
