Finding An IC

[Qiaozhi]

Hi Geo
Please explain more for me...
I've read a lot of articles that mentioned that Coil searches in the most time of you pulse
my pulse has a duty cycle of 97%
the coil should be disconnect in the 200us (=3%) and searches in 97%
Am I right?

my frequency is about 130Hz

my frequency is about 130Hz

When Tx signal turns off then after a small delay (10...50us) the loop receive the signal from the objects.
Example.... frequency =100Hz. Tx"on"= 500us Tx off= 9500us. Detector enabled 30us after the Tx signal tuns from on to off. That is all.
