But the characters take their form from a man's conception of the situation in which he finds himself. If the environment to which he is sensitive happens to be the smart set, he will imitate the character he conceives to be appropriate. That character will tend to act as modulator of his bearing, his speech, his choice of subjects, his preferences.
With regard to the latter, the key may be changed from time to time when taking Sol-fa work from hand signs or the modulator, or from Sol-fa notation, in order to get a wider range for the notes above mentioned.
In the better makes of microphone transformer, there is a third winding, called a side tone coil, to which a headphone can be connected so that the operator who is speaking into the microphone can listen-in and so learn if his transmitter is working up to standard. The Magnetic Modulator.
They had dined, and were now sitting in Gilbert's room in the lax attitude of people who have eaten well and are content. "Here we are," Gilbert went on, using his pipe as a modulator of his points, "four bright lads simply bursting with brains, and the question is, what is to become of us? The Boy: What Will He Become?
Where a single tube is used as an oscillator and a second tube is employed as a modulator, a reactor, which is a coil of wire wound on an iron core, is used in the plate circuit to keep the high voltage direct current of the motor-generator the same at all times. Likewise the grid circuit reactor is used to keep the voltage of the grid at a constant value. Connecting up the Apparatus.
In singing from the modulator this is possible to a certain extent, as the relation of each note to the key-note is shown roughly in distance by the dots between the notes. There is no such help given in the horizontal notation. In beginning the work in staff notation the notes of the scale will be thought of as steps in a ladder.
The required parts are the 50 watt tube; the grid leak resistance; the filament rheostat; the filament storage battery; and the magnetic modulator. It is not advisable to use an induction coil for the modulator for this set, but use, instead, either a telephone transformer, or better, a magnetic modulator of the second size which has an output of from 1-1/2 to 3-1/2 amperes.
As the magnetic modulator does the same thing a vacuum tube used as a modulator is not needed where the former is employed. For this reason a magnetic modulator is the cheapest in the long run. The Operation of Wireless Telephone Transmitters with Alternating Current.
For it must be remembered that, generally speaking, the effect of putting no question is to transfer into the other party's hands the entire originating movement of the dialogue; and thus, in a musical metaphor, the great man is the sole modulator and determiner of the key in which the conversation proceeds.
The magnetic modulator is described and pictured in this chapter. A 50 to 100 Mile Wireless Telephone Transmitting Set With 110 Volt Alternating Current.
