Abstract
Disclosed are an apparatus and method for processing a sensor signal. The apparatus for processing a sensor signal includes a sensing unit, an amplification unit configured to amplify an analog signal sensed by the sensing unit, an analog to digital converter (ADC) configured to convert the amplified analog signal into a digital signal having a first resolution, and a signal processor configured to process the digital signal with a numeral system having a second resolution or higher, allocate the processed digital signal to a message frame according to a regulated protocol, and output the message frame.
Claims8
An apparatus for processing a sensor signal, comprising:
- a sensing unit configured to sense an analog signal;
- an amplification unit configured to amplify the sensed analog signal;
- an analog-to-digital-converter (ADC) configured to convert the amplified analog signal into a digital signal having a first resolution;
- and
- a signal processor configured to process the digital signal with a numeral system having a second resolution, allocate the processed digital signal to a message frame according to the SENT protocol, and output the message frame as a SENT message frame;
- wherein the signal processor is configured to:
- allocate a remainder according to the numeral system to a first data region of the SENT message frame;
- and
- allocate a quotient according to the numeral system to a slow channel of a compatibility region or a second data region of the SENT message frame.
A method of processing a sensed analog signal, comprising:
- sensing an analog signal;
- amplifying the sensed analog signal;
- converting the amplified analog signal into a digital signal having a first resolution;
- processing the digital signal with a numeral system having a second resolution or higher;
- allocating the processed digital signal to a message frame according to a regulated protocol;
- and
- outputting the message frame;
- wherein the regulated protocol comprises a single-edge nibble transmission (SENT) protocol, and a message frame according to the SENT protocol comprises a SENT message frame;
- wherein the SENT message frame comprises a compatibility region comprising a tick time, a sync period and a slow channel, and a data region comprising a first data region and a second data region;
- and
- wherein outputting the message frame comprises:
- allocating a remainder according to the numeral system to the first data region of the SENT message frame, and
- allocating a quotient according to the numeral system to the slow channel of the compatibility region or the second data region.
