Researchers have demonstrated a low-cost digital system to efficiently measure unknown magnetic fields. Digital signals are the backbone of communication systems processed by hardware systems that transmit and receive the signals with the help of intermediate systems called ‘digital receiver systems’ or DRS.

A magnetometer is a device that measures magnetic field or magnetic dipole moment.
Some magnetometers measure the direction, strength, or relative change of a magnetic field at a particular location.
A compass is one such device, one that measures the direction of an ambient magnetic field, in this case, the Earth’s magnetic field.
