41Radio — is the transmission of signals, by modulation of electromagnetic waves with frequencies below those of visible light.Electromagnetic radiation travels by means of oscillating electromagnetic fields that pass through the air and the vacuum of… …
42Systematic code — In coding theory, a systematic code is one in which the input data are embedded in the encoded output. Similarly, a non systematic code is one in which the output does not contain the input bits. Such codes are used to add redundant information… …
43Communication with submarines — is difficult because radio waves do not travel well through thick electrical conductors like salt water. The obvious solution is to surface and raise an antenna above the water, then use ordinary radio transmissions. Early submarines had to… …
