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 + …)
Read moreWhat is the application of very high frequency signals?
In addition to VHF broadcasting, very high-frequency radio waves are widely used for ship and aircraft communications, disaster prevention and administration radio, police and fire radios, ham radio, and other applications .
Read moreWhat is the main advantage of low frequencies?
One advantage of lower frequencies is that the signals have better penetration , meaning they pass through objects such as walls with less attenuation. This effect results in better in-building penetration.
Read moreWhat is the application of frequency?
Frequency is an important parameter used in science and engineering to specify the rate of oscillatory and periodic phenomena, such as mechanical vibrations, audio signals (sound), radio waves, and light .
