A new modulation technique for AM broadcasting was demonstrated by industry pioneer Mike Dorrough at a recent meeting of SBE Chapter 43 in Sacramento. The Advanced Modulation System offers to increase ...

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 ...

Varying the voltage of a carrier or a direct current in order to transmit analog or digital data. Amplitude modulation (AM) is the oldest method of transmitting human voice electronically. In an ...

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 ...

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.

Belar Electronics has unveiled its latest innovations for analog and digital AM modulation, as the RF monitoring firm has completed its updates for its legacy AMMA-2. The company says this allows for ...

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 ...
