3.3 Receiver Working Mode

3.3.1 The working principle

When the cable is applied, a current is present on the cable, and the current generates
a magnetic field that radiates around the cable. The frequency of the magnetic field is
consistent with the frequency of the signal being applied. The strong and weak is that
the center of the cable decreases to the outer radiation, and the direction is the tangent
direction of a point in the radial circle.
Receiver through internal antenna or external input devices, respectively radiate to
receive cable of the magnetic field signals or leakage of electric field, use two
different kinds of working mode processing, the changes in the strength of the signal
hint to the operator.

3.3.2 Signal receiving mode - receiver operating mode
(1) Crest method (narrow peak, broad peak, broad peak arrow, crest + trough)

Peak Mode

The receiver has the strongest signal at the top of a particular signal cable. In the same
plane, the signal detected by the mobile receiver on the same plane attenuates
immediately, so it is named as the wave peak method. In fact, it USES the horizontal
antenna in the receiver to detect the magnetic field signal.
