High-power modulation. In an AM transmitter amplitude modulation of the carrier by introducing the modulating signal into the anode circuit of the final amplifying stage. The power of the modulating signal thus approximates to that at the transmitter output.  5, fiche 3, Anglais, - high%2Dpower%20modulation

Record number: 3, Textual support number: 2 CONT

Modulation is also identified as to level. High level modulation occurs when the modulating voltage is applied to the collector/plate circuit of the final power amplifier. With high level modulation, the final stage is operated class C and the preceding stages are also operated class C. The overall efficiency of such a transmitter is very high. A disadvantage of high level modulation is that comparatively high audio power is needed and several stages of voltage and power amplification may be required in the speech amplifier and modulator circuits.  4, fiche 3, Anglais, - high%2Dpower%20modulation

Fiche 4,  Justifications,  Anglais

Record number: 4, Textual support number: 1 CONT

An amplifier-based system having pulsed output includes an amplifier for amplifying a time varying voltage signal to produce an output voltage signal. A voltage-to-current(V-1) converter converts the output voltage signal into a current signal. An output stage including a current integrator integrates the current signal to generate an integrated voltage. An amplitude to time converter generates a pulse train from the integrated voltage, wherein a timing of the pulses in the pulse train represents the original time varying voltage signal. The pulse train representation permits transmission and accurate remote reconstruction of the original time varying voltage signal, such as signals generated by electrodes implanted inside a subject, including neural signals.  2, fiche 4, Anglais, - amplitude%2Dto%2Dtime%20converter
