Abstract
Techniques for filtering pressure pulse signals include receiving a pressure pulse signal, determining a wavelet filtering configuration, wherein the wavelet filtering configuration comprises at least one of number of levels or one or more coefficients, and generating a filtered pressure pulse signal based, at least in part, on the pressure pulse signal and a wavelet filter, wherein the wavelet filter is configured based the wavelet filtering configuration.
Claims20
A method for filtering a pressure pulse signal, the method comprising:
- receiving the pressure pulse signal;
- determining a first wavelet filtering configuration, wherein the first wavelet filtering configuration comprises at least one of a number of levels or one or more coefficients;
- and
- generating a first filtered pressure pulse signal based, at least in part, on the pressure pulse signal and a wavelet filter, wherein the wavelet filter is configured based on the first wavelet filtering configuration.
A system comprising:
- one or more computing systems comprising:
- one or more processors;
- and
- one or more non-transitory computer-readable mediums including instructions which, when executed by the one or more processors, cause the one or more processors to filter a pressure pulse signal using a wavelet filter, the instructions including:
- instructions to receive the pressure pulse signal;
- instructions to determine a first wavelet filtering configuration, wherein the first wavelet filtering configuration comprises at least one of a number of levels or one or more coefficients;
- and
- instructions to generate a first filtered pressure pulse signal based, at least in part, on the pressure pulse signal and the wavelet filter, wherein the wavelet filter is configured based on the first wavelet filtering configuration.
