*this device has input ports for each kind of frequency band (ranging widely from sub-sonic sound waves to radio to gamma and cosmic rays)
*user selects the range, accordingly the input port gets activated.
*the input port catches and displays the received noisy signal.
*the receiver is pre-installed with generally-used deciphering algorithms.
*special algorithms are used to detect the signal type and its respective deciphering algorithm
*post that the signal is tracked parallely to the pre-installed algo. and deciphering happens
*finally, a human readable data is obtained on a screen.
