[time-nuts] Questions about Austron 5000 Loran C receiver

[Bob Camp]

Hi

The concept you most commonly see is a curve fit approach. You know the structure of the waveform through several cycles. You can fit this "model waveform" to the observed data over a large number of points. As you fit more points, the impact of the noise is reduced.
