Demodulation is the process of extracting the baseband message from the modulated signals corrupted by noise so that it may be processed and interpreted by the intended receiver. This chapter describes various modulation and demodulation techniques that are used in communication systems.doi:10.1007/978-...
i.e., algebraically added. If both the carrier and the modulating signal are sine waves, the waveform resulting at the junction of the two resistors will be like that shown in Fig. 4-8(c), where the carrier wave is riding on the modulating signal. This signal is not AM. Modulation is...
Although this was a very crude method of modulation a radio carrier, the signals were audible over a distance of a few hundred metres, although there was a rasping sound caused by the spark.With the introduction of continuous sine wave signals, transmissions improved significantly, and AM soon...
In this context, "AM" refers to "Amplitude Modulation," a method of radio transmission. Unlike FM (Frequency Modulation), which is more common and offers clearer sound quality, AM uses amplitude modulation to transmit signals. This method is often used for long-distance communication, like ...

Amplitude modulation (AM) is a process by which the wave signal is transmitted by modulating the amplitude of the signal. Learn about amplitude modulation in detail here.

Methods and systems for reducing AM/PM distortion in a polar amplifier are disclosed and may comprise adding an offset signal to an amplitude signal in the digital domain and removing the offset signal in the analog domain during polar modulation. A sum of an amplitude signal and an offset sig...
