Question

What is the bandwidth of the signal that ranges from $40$ kHz $4$ MHz

• A. $36$ MHz
• B. $360$ kHz
• C. $3.96$ MHz
• D. $396$ kHz

Answer 1

- Bandwidth is defined as the difference between the highest and lowest frequencies of a given signal .

here highest frequency=4 MHZ ,lowest frequency=40 KHZ=0.04 MHZ

so bandwith=(4-0.04) MHZ =3.96 MHZ   ,OPTION (C)
