RF Modulators49

Radio Frequency (RF) modulator products are used to encode information onto a sinusoidal carrier signal by altering the carrier's amplitude, phase, and/or frequency. A receiving device performing the inverse, demodulation operation selectively receives an incoming signal at a desired carrier frequency, translating variations in carrier wave attributes back into its original form. Such an arrangement allows use of a communications channel for simultaneous transmission of multiple messages without interference between them.
