## 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.

## Claims

### Claim 1

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.

### Claim 2 (depends on 1)

The apparatus of claim 1, wherein the numeral system is a 2signal processor resolution numeral system.

### Claim 3 (depends on 2)

The apparatus of claim 2, wherein the numeral system is a 212 numeral system.

### Claim 4 (depends on 1)

The apparatus of claim 1, wherein the digital signal is uncompressed by the signal processor prior to the signal processor allocating the processed digital signal to the message frame.

### Claim 5

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.

### Claim 6 (depends on 5)

The method of claim 5, wherein outputting the message frame comprises processing the digital signal with a 2second resolution numeral system.

### Claim 7 (depends on 5)

The method of claim 5, wherein:
processing the digital signal is performed with a signal processor having a signal processor resolution; and
the numeral system is a 2signal processor resolution numeral system.

### Claim 8 (depends on 5)

The method of claim 5, wherein processing the data signal does not comprise compressing the digital signal prior to allocating the processed digital signal to the message frame.
