The three sub-intelligence disciplines in signal intelligence (SIGINT) are communications intelligence (COMINT), which involves intercepting and analyzing voice and data communications; electronic intelligence (ELINT), which focuses on collecting and interpreting electronic signals emitted by non-communication devices, such as radar; and foreign instrumentation signals intelligence (FISINT), which pertains to the collection of data from foreign weapons systems and technological devices. Together, these disciplines help to gather critical information about adversaries' capabilities and intentions.

The six sub-disciplines of MASINT are radar, radio frequency, geophysical, nuclear radiation, materials, and electro-optical.

If three pure signals with frequencies of 100, 200, and 500 Hz are added, their sum is a signal with afrequency of 100 Hz, which has additional "wiggles" superimposed on its shape. The wiggles appear ingroups of 2 per cycle and 5 per cycle on the main signal; their exact shape and depth is determined bythe relative amplitudes of the three individual component signals.
