MSP430FR6043: Don`t understand the formula of the signal handling

Hello,

As mentioned in the document earlier, Z(-1), Z0, Z(+1) are the correlation values with offset -1, 0, +1 respectively.

Delta is the Delta time of flight obtained as the position in time where the correlation is the highest and obtained as an interpolation of the 3 values Z(-1), Z0, Z(+1), as mentioned in equation 9.

Hello,

Usually m = 0. But in general, m is an integer sample offset where the correlation between the received signal 1 & 2 from the 2 transducers is done with a sample offset of m samples.

Hello,

That formula is still for the differential time of flight. And there is only one differential time of flight. I guess, we should have just DToF = instead of T12.
