Show all Magnetic Receivers Manufacturers  Magnetic receivers
use the electromagnetic principle to receive and analyze
signals. An electromagnetic principle can be defined as electric
currents running along a wire that produce magnetic forces and
rotating magnets around a wire produce electricity. The simplest
example of a magnetic receiver is the telephone. A magnetic
receiver in a telephone converts the analog electrical signals
back into acoustical energy. Signal receivers are used in
television transmissions, and are used to receive cable and
satellite transmissions. A signal receiver device receives
broadcast signals and detects rating or category codes therein.
The signal receiver compares the detected code to a setting set
in the device. If the comparison indicates that the incoming
signal has a rating greater than that set or is of an undesired
category the broadcast signal is blocked or an alert is given.
Magnetic receivers and signal receivers may be tamper-resistant
in certain devices to prevent di
