What is the bandwidth of a signal that ranges from 1 MHz to 4 MHz?Select one:-3 MHz3 MHz1 MHz4 MHz

Break Down the Problem

1. Identify the frequency range of the signal.
2. Calculate the bandwidth by finding the difference between the upper and lower frequency limits.

Relevant Concepts

• Bandwidth is calculated as: $\text{Bandwidth} = \text{Upper Frequency} - \text{Lower Frequency}$

Analysis and Detail

1. The lower frequency is 1 MHz.
2. The upper frequency is 4 MHz.
3. Applying the formula: $\text{Bandwidth} = 4\, \text{MHz} - 1\, \text{MHz} = 3\, \text{MHz}$

Verify and Summarize

The calculations confirm that the bandwidth has been correctly determined. The range between 1 MHz and 4 MHz yields a bandwidth of 3 MHz.

Final Answer

The bandwidth of the signal is 3 MHz.
