pi metal detector schematic
i am trying to build a PI metal detector
for it i made the research, which states that with the presence of the metal the pwidth of the decaying pulse increases
can any one guide me how to made a circuit that could detect the width of the decaying pulse and with this we can detect the presence of the metal
or
how the commercial Loop detector work
i searched and found this schematic that is of the Pulse induction type ,
**broken link removed**
please help me that how can a peak of 120 to 150 vlts can be measured by this ciruit
and what is the rule of the integrator amplifier
