Amplitude-shift-keying (ASK) radio-frequency (RF) signal decoding device and method thereof

An amplitude-shift-keying radio frequency (ASK RF) signal decoding method, comprising:

• separating a low frequency signal and a high frequency signal from the ASK RF signal including a pause section and a non-pause section;
• generating a divided signal by dividing the high frequency signal;
• counting the divided signal for the non-pause section of the low frequency signal;
• decoding the ASK RF signal based on a result of the counting;
• and
• generating decoded data, wherein, when first decoding data is a first logic level, the step of generating the decoded data comprises:
• performing a first decoding of second decoding data of the first logic level as data output next to the first decoding data when the result of the counting is smaller than a first threshold value;
• performing second decoding of third decoding data of a second logic level as data output next to the first decoding data when the result of the counting is greater than the first threshold value;
• decoding fourth decoding data of the second logic level as data output next to the third decoding data when the result of the counting is smaller than a second threshold value;
• and
• decoding fifth decoding data of the first logic level as data output next to the third decoding data when the result of the counting is greater than the second threshold value.
