Abstract

Systems and methods for creating and using a conditioning signal are provided. In some embodiments, systems for creating a conditioning signal providing information regarding an input signal are provided, wherein the systems comprise: a signal conditioning developer that receives the input signal and produces the conditioning signal; a delay device that receives the input signal and produces a delayed input signal, wherein the delayed input signal is delayed to simultaneously transmit with the conditioning signal and form a vector signal with the delayed input signal and the conditioning signal; and a receiving circuit coupled to the signal conditioning developer and the delay device that receives the vector signal and dynamically adjusts according to the conditioning signal.

Claims

1. A system for creating and using a conditioning signal providing information regarding an analog input signal comprising:

a signal conditioning developer that receives the analog input signal and produces the conditioning signal;

a delay device that receives the analog input signal and produces a delayed input signal, wherein the delayed input signal is delayed to simultaneously transmit with the conditioning signal; and

an amplitude digitizer coupled to the signal conditioning developer and the delay device, the amplitude digitizer being configured to receive the delayed input signal and the conditioning signal and to quantize the delayed input signal, wherein the amplitude digitizer uses level line thresholds and times at which the level line thresholds are crossed to digitally represent the delayed input signal.

2. The system of claim 1, wherein the conditioning signal includes information relating to at least one of acceptable distortion level and bias, and the amplitude digitizer dynamically adjusts the at least one of acceptable distortion level and bias according to the conditioning signal information.

3. The system of claim 1, further comprising a computer readable medium storing a digital signal vector comprising the delayed input signal and the conditioning signal.

4. The system of claim 1, wherein the amplitude digitizer quantizes the delayed input signal based on information provided by the conditioning signal.

5. The system of claim 4, further comprising a computer readable medium storing a digitized vector signal comprising a delayed input signal that was digitized using the conditioning signal and a digitized conditioning signal.

6. A method for creating and using a conditioning signal providing information regarding an analog input signal comprising:

deriving from an analog input signal a conditioning signal that contains information regarding how a receiving circuit is to handle the analog input signal;

delaying the analog input signal producing a delayed input signal to synchronize the analog input signal with the conditioning signal;

receiving the conditioning signal and the delayed input signal at an amplitude digitizer; and

quantizing the delayed input signal using level line thresholds and times at which the level line thresholds are crossed to digitally represent the delayed input signal.

7. The method of claim 6, wherein the conditioning signal includes information relating to at least one of acceptable distortion level and bias, and the amplitude digitizer dynamically adjusts the at least one of acceptable distortion level and bias according to the conditioning signal information.

8. The method of claim 6, further comprising storing a digital signal vector pair in a computer readable medium comprising the delayed input signal and the conditioning signal.

9. The method of claim 6, wherein the quantizing of the delayed input signal using amplitude digitizing is based on information provided by the conditioning signal.

10. The method of claim 9, further comprising quantizing the input signal using amplitude digitizing and storing a digitized vector signal comprising a delayed input signal that was digitized using the conditioning signal and a digitized conditioning signal.

11. A system for creating and using a conditioning signal providing information regarding an analog input signal comprising:

a means for receiving the analog input signal and producing the conditioning signal;

a means for delaying the analog input signal and producing a delayed input signal that is delayed to simultaneously transmit with the conditioning signal; and

a means for amplitude digitizing coupled to the means for receiving and the means for delaying that receives the delayed input signal and the conditioning signal and the means for amplitude digitizing quantizes the delayed input signal, wherein the means for amplitude digitizing uses level line thresholds and times at which the level line thresholds are crossed to digitally represent the delayed input signal.

12. The system of claim 11, wherein the conditioning signal includes information relating to at least one of acceptable distortion level and bias, and the means for amplitude digitizing dynamically adjusts the at least one of acceptable distortion level and bias according to the conditioning signal information.

13. The system of claim 11, further comprising a means for storing a digital signal vector comprising the delayed input signal and the conditioning signal.
