Abstract
A signal reader system having a processor for reconstructing a relatively high-frequency input signal to a low-pass filter from an output of the filter based on a characterization of the filter. The characterization may be adapted to compensate for filter output changes due to temperature. A signal reader may be connected to the output of the processor to determine certain things, such as a pulse count, about the filter input signal.
Claims20
A pulse counting system comprising:
- a filter;
- an analog-to-digital converter connected to the filter;
- and
- an algorithmic processor connected to the analog-to-digital converter;
- and
- wherein the algorithmic processor is for reconstructing an input signal of the filter.
3 more elements
A method for counting pulses comprising:
- processing an output signal from a filter to obtain a reconstruction of an input signal to the filter;
- and
- counting pulses of the reconstruction of the input signal.
A signal reader system comprising:
- a filter;
- a signal reconstructor connected to the filter;
- and
- a signal reader connected to the signal reconstructor;
- and
- wherein the signal reconstructor is for reconstructing an input signal of the filter.
