What is spectrum of modulated signal?
Amplitude modulation spectrum of two sine waves, carrier C and modulator M, showing the addition of a pair of sidebands, C + M and C - M, around the carrier. The amplitude of the modulating signal controls the amplitude of the carrier frequency, as well as that of the sidebands, in the resulting spectrum.
What is spectrum of frequency modulation?
Spectra of FM signals. Frequency modulation varies the frequency of a sine wave carrier depending on the source signal. The difference between the instantaneous and center frequency of the carrier is proportional to the modulating signal's instantaneous amplitude.
What would happen if a 1 kHz signal amplitude modulated a 1 kHz carrier signal?
Sidebands. It is possible to plot the frequency spectrum of an AM transmission using a spectrum analyser. If a 1 kHz sine wave tone is modulated onto a 1 MHz carrier, two sidebands will be produced 1 kHz above and 1 kHz below the 1 MHz carrier signal.
What is modulated signal?
Modulation is the process of converting data into radio waves by adding information to an electronic or optical carrier signal. A carrier signal is one with a steady waveform -- constant height, or amplitude, and frequency.
