Abstract
A device and method for determining pulses in a modulated signal is disclosed. The modulated signal is processed and converted into a quantized analog type of digital data stream. The data stream is evaluated over time by considering preceeding and subsequent values in the data stream to generate a filtered wave form. By using extreme values in the filtered wave form pulse detection is accurately determined regardless of whether the modulated signal has complicating features, such as dicrotic notch, or high noise levels, or both.
