Signal Filtering Method and Electronic Device
First Claim
1. A signal filtering method provided for filtering a plurality of signals obtained by an electronic device at a plurality of time points, wherein each of the signals obtained at an i-th time point of the above time points corresponds to an i-th value, the i-th value and an (i+1)-th value are defined as an i-th ordering sequence, i is a positive integer, each of the i-th ordering sequence and an (i+1)-th ordering sequence conforms to a first strict monotonicity, and the method comprises:
- (a) determining whether an (i+2)-th ordering sequence conforms to a second strict monotonicity, and executing step (b) if the (i+2)-th ordering sequence conforms to the second strict monotonicity; and
(b) determining whether an (i+3)-th ordering sequence conforms to the second strict monotonicity, and deleting a signal obtained at an (i+3)-th time point if the (i+3)-th ordering sequence does not conform to the second strict monotonicity.

Abstract
A signal filtering method for filtering signals obtained at a number of time points by an electronic device is provided. Each of the signals corresponds to an i-th value at an i-th time point of the abovementioned time points, and the i-th value and an (i+1)-th value are defined as an i-th ordering sequence, wherein i is a positive integer. Each of the i-th ordering sequence and an (i+1)-th ordering sequence conforms to a first strict monotonicity. The method includes the following steps. Firstly, whether an (i+2)-th ordering sequence conforms to a second strict monotonicity is determined. If yes, then execute the next step. Determine whether an (i+3)-th ordering sequence conforms to the second strict monotonicity. If not, a signal obtained at an (i+3)-th time point is deleted.

7. An electronic device, comprising:
-
a fetching unit for fetching a plurality of signals obtained at a plurality of time points having an equal interval between two adjacent time points, wherein each of the signals obtained at an i-th time point of the above time points corresponds to an i-th value, the i-th value and an (i+1)-th value are defined as an i-th ordering sequence, i is a positive integer, and each of the i-th ordering sequence and an (i+1)-th ordering sequence conforms to a first strict monotonicity; a determining unit for determining whether an (i+2)-th ordering sequence conforms to a second strict monotonicity, and for determining whether an (i+3)-th ordering sequence conforms to the second strict monotonicity; and a filtering unit for filtering the signals obtained by the fetching unit, wherein if the determining unit determines that the (i+2)-th ordering sequence conforms to the second strict monotonicity but the determining unit determines that the (i+3)-th ordering sequence does not conform to the second strict monotonicity, then the filtering unit deletes a signal obtained at an (i+3)-th time point. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15, 16, 17)

18. An electronic device used for an application program to filter a plurality of signals obtained at a plurality of time points having an equal interval between two adjacent time points, wherein each of the signals obtained at an i-th time point of the above time points corresponds to an i-th value, the i-th value and an (i+1)-th value are defined as an i-th ordering sequence, i is a positive integer, each of the i-th ordering sequence and an (i+1)-th ordering sequence conforms to a first strict monotonicity, and the electronic device comprises:
-
a memory for storing a programming code of an operating system; and a processor used for reading and executing the programming code of the operating system and then executing the application program to filter the signals, wherein the processor is for determining whether an (i+2)-th ordering sequence conforms to a second strict monotonicity, and for determining whether an (i+3)-th ordering sequence conforms to the second strict monotonicity, and if the processor determined that the (i+2)-th ordering sequence conforms to the second strict monotonicity but the (i+3)-th ordering sequence does not conform to the second strict monotonicity, then the processor deletes a signal obtained at an (i+3)-th time point. - View Dependent Claims (19, 20, 21, 22)
