... Pulse Amplitude Modulation is a form of signal modulation where the message information is encoded in the amplitude of a series of signal pulses. The output is a series of pulses, the amplitude of which vary in proportion to the modulating signal. The samples are taken at regular interval of time. ...

ECE 4117 Experiment 3 Frequency Modulation ECE 4117
... Frequency Modulation (FM) modulates a carrier signal by varying the frequency of carrier signal with respect to the message signal. Over time, the frequency would be varied by an arbitrary factor multiplied the current amplitude of the message signal at that point in time. Since this is the case, th ...

Battle of the Beams
The Battle of the Beams was a period early in the Second World War when bombers of the German Air Force (Luftwaffe) used a number of increasingly accurate systems of radio navigation, mainly developed by Johannes Plendl, for night bombing in the United Kingdom. British scientific intelligence at the Air Ministry fought back with a variety of their own increasingly effective means, involving jamming and distortion of the radio waves. The period ended when the Wehrmacht moved their forces to the East in May 1941, in preparation for the attack on the Soviet Union.
