A small correction/clarification to the paragraph on the effect phase
detector gain error.
The input sinewave amplitude only has to be known to within a few (5%)
percent to keep the effective sawtooth correction error due to the phase
detector gain uncertainty under 1ns when using an M12+T or M12M GPS timing
receiver.In principle the ADC can be used to measure the amplitude of its
input sinewave, such calibration conversions being interleaved between
successive PPS pulses.
