Amplitude modulation was used in experiments of multiplex telegraph and telephone transmission in the late 1800s. [4] However, the practical development of this technology is identified with the period between 1900 and 1920 of radiotelephone transmission, that is, the effort to send audio signals by radio waves. The first radio transmitters, called spark gap transmitters, transmitted information by wireless telegraphy, using pulses of the carrier wave to spell out text messages in Morse code. They could not transmit audio because the carrier consisted of strings of damped waves, pulses of radio waves that declined to zero, and sounded like a buzz in receivers. In effect they were already amplitude modulated. US 4580111, Swanson, Hilmer,"Amplitude modulation using digitally selected carrier amplifiers",published 1986-04-01, assigned to Harris Corp

In the diagram, the unmodulated carrier has an amplitude of 1. Modulation methods [ edit ] Anode (plate) modulation. A tetrode's plate and screen grid voltage is modulated via an audio transformer. The resistor R1 sets the grid bias; both the input and output are tuned circuits with inductive coupling. A(t) represents the time-varying amplitude of the sinusoidal carrier wave and the cosine-term is the carrier at its angular frequency ω {\displaystyle \omega } , and the instantaneous phase deviation ϕ ( t ) {\displaystyle \phi (t)} . This description directly provides the two major groups of modulation, amplitude modulation and angle modulation. In angle modulation, the term A( t) is constant and the second term of the equation has a functional relationship to the modulating message signal. Angle modulation provides two methods of modulation, frequency modulation and phase modulation.Admittedly, I am playing “Doubting Thomas” on the yellowing-in the-sun issue. If CC does not yellow while exposed to the elements and bombarded by UV, then it will be the first epoxy I have encountered to not yellow or chalk-out. Considering how truly clear CC is, especially the hardener, if any epoxy is capable of not yellowing, it might just be this one. Even if it does eventually yellow, I doubt it will be to the extent of the others. One way of the other, I consider it a small price to pay for an outstanding product. Hopkins, D. W., Chudek, J.

Modulation circuit designs may be classified as low- or high-level (depending on whether they modulate in a low-power domain—followed by amplification for transmission—or in the high-power domain of the transmitted signal).
