Equalizer for limited intersymbol interference

A method comprising:

• obtaining a waveform describing a signal from a memory;
• extracting, via a processor, a signal impulse response from the waveform;
• selecting, by the processor, a window function based on a shape of the signal impulse response;
• and
• applying, by the processor, the window function to the signal impulse response to remove Intersymbol Interference (ISI) outside a window of the window function;
• wherein extracting the signal impulse response from the waveform comprises extracting a step response from the waveform and deriving the signal impulse response from the step response, or deriving the signal impulse response from S-parameters.

A non-transitory computer readable medium for storing a computer program product comprising instructions that, when executed by a processor of a test and measurement system, cause the test and measurement system to:

• obtain a waveform describing a signal from a memory;
• extract a signal impulse response from the waveform;
• select a window function based on a shape of the signal impulse response;
• and
• apply the window function to the signal impulse response to remove Intersymbol Interference (ISI) outside a window of the window function;
• wherein extracting the signal impulse response from the waveform comprises extracting a step response from the waveform and deriving the signal impulse response from the step response, or deriving the signal impulse response from S-parameters.
