Abstract

An apparatus for processing input signals includes a signal receiver, a comparator, first and second drivers, and a calculator. The signal receiver is used for receiving input signals. The comparator compares the input signals with predetermined signals and generates unit signals representing a corresponding comparison result. The first driver generates first drive signals according to the unit signals. The calculator generates a result signal according to the unit signals. The second driver generates a second drive signal according to the result signal.

Claims

1. An apparatus for processing at least one input signal comprising:

a signal receiver for receiving the at least one input signal;

a comparator for comparing the at least one input signal with at least one corresponding predetermined signal, and generating at least one unit signal representing a corresponding comparison result;

a first driver for generating at least one first drive signal according to the at least one unit signal;

a calculator for generating a result signal according to the at least one unit signal; and

a second driver for generating a second drive signal according to the result signal.

2. The apparatus of claim 1, wherein the at least one unit signal represents a qualification status of the corresponding input signal.

3. The apparatus of claim 2, further comprising at least one light capable of being driven by the corresponding first drive signal to indicate the qualification status of the corresponding input signal.

4. The apparatus of claim 1, further comprising a light capable of being driven by the second drive signal to indicate a qualification status of a signal source from which the at least one input signal is generated.

5. The apparatus of claim 4, further comprising an alarm capable of being driven by the second drive signal to sound if the result signal indicates the signal source as unqualified.

6. The apparatus of claim 4, wherein the calculator determines the signal source as unqualified if any one of the at least one unit signal represents the corresponding input signal as unqualified, and determines the signal source as qualified if all unit signals represents the corresponding input signal as qualified.

7. The apparatus as described in claim 1, further comprising a register for storing a tag of the at least one input signal.

8. The apparatus as described in claim 7, wherein the register comprises at least one tag space corresponding to the at least one input signal.

9. The apparatus as described in claim 8, wherein the register is configured for generating a status signal indicating a storage status of the at least one tag space.

13. The method as described in claim 1, further comprising:

determining the signal source as qualified if all unit signals indicate the corresponding at least one input signal as qualified.

14. The method as described in claim 13, further comprising:

registering a tag of the at least one input signal;

determining the signal source as qualified if all tags of the input signals are registered and all of the at least one unit signal indicates the corresponding at least one input signal as qualified.

10. A method for receiving at least one input signal comprising:

receiving the at least one input signal;

comparing the at least one input signal with a corresponding predetermined signal, and generating a unit signal accordingly;

indicating the unit signal;

determining qualification status of a signal source of the at least one input signal according to the corresponding unit signal; and

indicating the determination.

11. The method as described in claim 10, wherein the unit signal indicates the qualification status of the corresponding input signal.

12. The method as described in claim 11, further comprising:

determining the signal source as unqualified if any one unit signal indicates the corresponding at least one input signal as unqualified.
