Question

Given baseband message signals that have bandwidth of 25KHz, please calculate the maximal number of SSB channels allowed in the frequency range

of 500KHZ-3000KHZ.
Select one:
a. 140
b. 120
c. 100
d. 50

Answer 1

The maximal number of Single Sideband (SSB) channels that can be accommodated in the frequency range of 500 KHz to 3000 KHz, with each channel having a bandwidth of 25 KHz, is 100 channels.

Step-by-step explanation:

To calculate the maximal number of Single Sideband (SSB) channels allowed in the frequency range of 500 KHz to 3000 KHz, given that each baseband message signal has a bandwidth of 25 KHz, we need to determine how many non-overlapping 25 KHz slots fit into the total available spectrum.

The total available frequency range for SSB channels is:

3000 KHz - 500 KHz = 2500 KHz

Now, to find the number of 25 KHz SSB channels that can fit into the 2500 KHz range, we divide the total range by the bandwidth of a single SSB channel:

2500 KHz / 25 KHz per channel = 100 channels

Therefore, a maximum of 100 SSB channels can be accommodated in the specified frequency range. The correct answer is c. 100.
