Fast |
Fast correlation of a maximum length sequence with a signal. The result is the response function of the system under test. See remarks for detail.

| Execute | Executes the correlation. |
 | Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object) |
| GetHashCode | Serves as the default hash function. (Inherited from Object) |
| GetType | Gets the Type of the current instance. (Inherited from Object) |
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object) |
| ToString | Returns a string that represents the current object. (Inherited from Object) |
Remarks
The response function of a device under test (DUT) can be determined with the help of maximum length sequences as followed. The maximum length sequence is used to generate a input signal for the DUT.
The DUT will respond to this input signal. As a result, it will generate a output signal. To get the response function of the DUT, the output signal of the DUT should be correlated with its input signal.
As a simplification, here the output signal of the DUT is correlated with the maximum length sequence itself. This means that the DUT here includes the generation of the output signal.
