How do you draw a frequency spectrum in AM?
Frequency spectrum of AM.
Amplitude of each side band is mVc2 where m is modulating index. If we plot freq on x-axis and respective amplitude on y-axis, we get freq spectrum of AM.
What is frequency spectrum of AM wave?
The frequency band used for AM radio is about 550 to 1720 kHz. This is the range of carrier frequencies available. The information transmitted is music and talk which falls in the audio spectrum. The full audio spectrum ranges up to 20 kHz, but AM radio limits the upper modulating frequency to 5 kHz.
How do you find the frequency spectrum of a signal?
Frequency spectrum of a signal is the range of frequencies contained by a signal. For example, a square wave is shown in Fig. 3.5A. It can be represented by a series of sine waves, S(t) = 4A/π sin(2πft) + 4A/3π sin(2π(3f)t) + 4A/5π sin(2π(5f)t + …)
How do you make AM waves?
To produce an amplitude modulated wave we need to superimpose this signal with another signal of higher frequency. This signal is the 'Carrier Signal' and differs from one carrier to another.
