why the ZCD has a pot R 22 ?
D1 , on the envelope detector.
On the 4052, why we need -5 V?
What I mean if we send pulse 1 , the corresponding reversed pulsed will be after 300 other pulses
It looks like if the diff is less than 200 (ie half period), then you add a pulse.
about transducers behavior and define Northerror .
Even you mentioned that we do not have individual Tof, I think we do have it, since envelope measures that
My question to you is how do you know that this is needed?
pick the signal from the sending end
it gave me unreal and constant values
two pin one is short and another one is long
