A method of analyzing a pulse modulated signal, said method comprising:
- receiving a pulse modulated signal;
- determining a dynamic threshold level based on a period of said pulse modulated signal and said pulse modulated signal;
- and
- demodulating said pulse modulated signal by said dynamic threshold level,
- wherein a decimation interval is determined based on said period of said pulse modulated signal, and
- wherein either a mean value and a root mean square value are determined within said decimation interval or a maximum value and a minimum value are determined within said decimation interval, said dynamic threshold level corresponding to half of the difference of said maximum value and said minimum value.
A signal analysis instrument for analyzing a pulse modulated signal, the signal analysis instrument comprising an input, a signal processing circuit, a comparator, and a signal output,
- wherein said input receives a pulse modulated signal,
- wherein said signal processing circuit determines a dynamic threshold level based on a period of said pulse modulated signal and said pulse modulated signal,
- wherein said comparator receives said dynamic threshold level and said pulse modulated signal,
- wherein said comparator demodulates said pulse modulated signal while taking said dynamic threshold level and said pulse modulated signal into consideration,
- wherein said signal processing circuit determines a decimation interval based on said period of said pulse modulated signal, and
- wherein either said signal processing circuit determines a mean value and a root mean square value within said decimation interval or said signal processing circuit determines a maximum value and a minimum value within said decimation interval, said dynamic threshold level corresponding to half of the difference of said maximum value and said minimum value.
A method of analyzing a pulse modulated signal, said method comprising:
- receiving a non-static pulse modulated signal;
- determining a dynamic threshold level based on a period of said pulse modulated signal and said pulse modulated signal;
- and
- demodulating said pulse modulated signal by said dynamic threshold level,
- wherein the dynamic threshold level used for demodulating the pulse modulated signal is automatically adapted with regard to the pulse modulated signal to be analyzed such that a respective individual threshold level value is applied on each individual sample of the pulse modulated signal.
