Modulation is the act of translating some low-frequency or baseband signal (voice, music, and data) to a higher frequency. Why do we modulate signals? There are at least two reasons: to allow the ...
FREQUENCY-MODULATION, or the technique of varying the frequency of radio waves for signalling purposes, has been known and used for many years ; but it was not until Armstrong in the United States in ...
The circuit was designed to function on the middle of the FM band, 98 MHz, since the FM frequency ranges from 88 MHz to 108 MHz. Transmitter – an electronic device that can produce or amplify a ...
Bacteria employ complex signaling networks for adaptive gene control in changing environments. Bacterial second messenger molecules such as cyclic AMP (cAMP) relay external environmental signals into ...
