pyecsca.sca.trace.filter module
Provides functions for filtering traces using digital (low/high/band)pass and bandstop filters.

filter_lowpass(trace, sampling_frequency, cutoff)[source]
Apply a lowpass digital filter (Butterworth) to trace, given sampling_frequency and cutoff frequency.
 Parameters:
trace (Trace
)
sampling_frequency (int
)
cutoff (int
)
 Return type:
Trace
 Returns:


filter_highpass(trace, sampling_frequency, cutoff)[source]
Apply a highpass digital filter (Butterworth) to trace, given sampling_frequency and cutoff frequency.
 Parameters:
trace (Trace
)
sampling_frequency (int
)
cutoff (int
)
 Return type:
Trace
 Returns:


filter_bandpass(trace, sampling_frequency, low, high)[source]
Apply a bandpass digital filter (Butterworth) to trace, given sampling_frequency, with the passband from low to high.
 Parameters:
trace (Trace
)
sampling_frequency (int
)
low (int
)
high (int
)
 Return type:
Trace
 Returns:


filter_bandstop(trace, sampling_frequency, low, high)[source]
Apply a bandstop digital filter (Butterworth) to trace, given sampling_frequency, with the stopband from low to high.
 Parameters:
trace (Trace
)
sampling_frequency (int
)
low (int
)
high (int
)
 Return type:
Trace
 Returns:
