1) A radio receiver has two main functions to perform: firstly, it has to select the required radiation from all the other electromagnetic waves that are present over the surface of the Earth, and secondly, it has to separate (or demodulate) the audio-frequency current from the radio-frequency carrier. 2) In the receiver these signals, which are close to each other in frequency, have to be amplified and separated. 3) The second function of a receiver is to demodulate the earner-wave; again, this operation can be performed by using an electronic valve. 4) They said that the separator contained two resonant circuits, one tuned to the frequency of the sound carrier-wave. 5) During this time the spot of light has covered the whole screen twice, but owing to the persistence of the fluorescent coating of the tube, the whole screen is illuminated.
