telephony but also used for circuit- and packet-
switched data communications.
I/Q data
–
Recording an I/Q demodulated signal enables
the reconstruction and analysis of signal
characteristics of any complexity. The RF signal
is represented by the components I and Q,
resulting from the complex output signal of a
base-band demodulation (I/Q demodulation).
• I data: Real part (In-phase)
• Q data: Imaginary part (Quadrature-phase)

through amplitude modulation.
Magnetic
Declination
Magnetic declination
Describes the angle between the geographic
(true) and the magnetic North and is used to
correct the compass reading at a given location.
You can find the declination values for any
location at (e.g.):
