Modulation is fundamental to electronic communications. The modulating signal might be analog in nature (voice or music) or digital bit streams. Most modern communication systems are digital, using ...

The total power content of an AM signal is 1000 W. Determine the power being transmitted at the carrier frequency and at each of the sidebands when the percent modulation is 100%. The total power ...

Modulation is the process of varying a higher frequency carrier wave to transmit information. Though it is theoretically possible to transmit baseband signals (or information) without modulating it, ...

Amplitude modulation (AM) is by far the oldest form of modulation known. The first broadcast stations were AM, but even earlier, CW or continuous-wave signals with Morse code were a form of AM.

Have you ever heard terms like modulation scheme, orthoganal frequency division multiplexing (OFDM), or symbol rate and scratched your head? As new wireless standards emerge, we get excited about the ...

Overcoming the issues of DC offset in Direct Conversion for Software Defined Radios. Modulation is a process by which characteristics of a high-frequency carrier signal are altered to convey ...

The process of varying the amplitude of a sound, often periodically. An example of AM is the violinist's tremolo, where the amplitude of the vibrating string is rapidly altered by a movement of the ...
