But, in order to the IR estimation be correct, there must be a synchronization between the clock frequencies of the: (1) D/A converter at the output generator and the (2) A/D converter on the input recorder. If the "sampling ticks" of these clocks are not (at least approximately) synchronized, then a significant error is expected on the estimate.<br>

As long as they are on the same card, they will be in perfect sync at the clock level unless you have some really unusual hardware. This is because the same clock is used for A/D and D/A. Usually they are on the same chip and the data from the ADC is clocked out using the same clock that loads the DAC.<br>
