Answer to Question #204291 in Physics for omar

Question

a radio signal has a centre frequency of 202.2 MHz and a bandwidth of 300 kHz. What are the highest and lowest frequencies in the signal spectrum?

Answer 1

The half of the bandwidth is $300kHz/2 = 150KHz = 0.15MHz$. Then the lower boundary is:

$$f_1 = 202.2MHz + 0.15MHz = 202.35MHz$$

The upper boundary:

$$f_2 = 202.2MHz - 0.15MHz = 202.05MHz$$

Answer. (202.05MHz, 202.35MHz)
