Frequency Modulation (or FM) synthesis is a simple and powerful method for creating and controlling complex spectra, introduced by John Chowning of Stanford University around 1973. In its simplest ...

AM, or amplitude modulation, was the earliest way of sending ... The video covers the math of what you probably already know: AM has a carrier and two identical side bands. SSB suppresses the ...

The transmission of a fixed frequency that has been altered (modulated) to "carry" data ... The receiving device detects the steady 2.5 GHz carrier and demodulates it to obtain the data within.

He took care to transmit a clear signal by watching the modulated wave on an oscilloscope ... Due to the low 40 kHz carrier frequency, the sound lacks the higher audio frequencies.

The difference is in how the carrier wave is modulated, or altered ... varied to incorporate the sound information. With FM, the frequency (the number of times each second that the current ...
