Abstract
A method, system, and computer readable medium are provided for monitoring a signal source. The illustrative method includes receiving an analog signal from the signal source, converting the analog signal into a digital signal having a frequency that is representative of an amplitude of the analog signal, and monitoring at least one parameter of the analog signal by counting features of the digital signal or time-measuring a distance between the features of the digital signal.
Claims20
A method of monitoring a signal source, the method comprising:
- receiving an analog signal from the signal source;
- converting the analog signal into a digital signal having a frequency that is representative of an amplitude of the analog signal;
- and
- monitoring at least one parameter of the analog signal by counting features of the digital signal or time-measuring a distance between the features of the digital signal.
A system for monitoring a signal source, the system comprising:
- a receiver comprising a current controlled oscillator that converts an input analog signal into a digital signal having a frequency that represents a parameter of the analog signal;
- and
- a digital signal processor that receives the digital signal and monitors the parameter of the analog signal by counting features of the digital signal or time-measuring a distance between features of the digital signal.
A computer readable medium comprising instructions, which when executed by a processor, cause the processor to:
- generate a parameter selection signal, the parameter selection signal enabling different parameters from among a plurality of candidate parameters of an analog signal to be selected as a selected parameter;
- receive a digital signal having a frequency that represents the selected parameter of the analog signal;
- and
- monitor the selected parameter of the analog signal by counting features of the digital signal or time-measuring a distance between the features of the digital signal.
