Answer 1

Answer: What is the bandwidth of a signal that can be decomposed into five sine waves with frequencies?

220 ns = 220 x 10 -9 s = is the bandwidth of a signal that can be decomposed into five sine waves with frequencies at 0, 20, 50, 100, and 200 Hz? All peak amplitudes are the same.

Explanation:

Answer 2

Answer:

The band width of the signal is 200Hz.

Explanation:

Given five sine waves with frequencies 0, 20, 50, 100, and 200 Hz.

Bandwidth defines the frequency range of a signal.

The bandwidth of a periodic composite signal is given by the difference between the upper and lower frequencies contained in that signal.

Here, the lowest frequency, $f_l=0Hz$

And the highest frequency, $f_h=200Hz$

The difference between the frequencies is the bandwidth B of the given signal.

$\therefore B=f_h-f_l=200-0=200Hz$.

Therefore, the band width of the signal is 200Hz.

Let us take the peak amplitude of the signals as 5V and draw the bandwidth diagram.
