Question

A corporation has a medium with a 10−MHz bandwidth (lowpass). The corporation needs to create 10 separate independent channels each capable of sending at least 10Mbps. The company has decided to use QAM technology. What is the minimum number of bits per baud for each channel? What is the number of points in the constellation diagram for each channel?

Answer 1

The minimum number of bits per baud for each channel is 1. The number of points in the constellation diagram for each channel is 2.

Step-by-step explanation:

To calculate the minimum number of bits per baud for each channel, we need to use the formula:

Minimum number of bits per baud = bandwidth / data rate,

where the bandwidth is given as 10 MHz and the data rate is given as 10 Mbps. Using these values, we can calculate:

Minimum number of bits per baud = 10 MHz / 10 Mbps = 1 bit per baud.

To calculate the number of points in the constellation diagram for each channel, we need to use the formula:

Number of points = 2^(bits per baud).

Since the minimum number of bits per baud is 1, the number of points in the constellation diagram for each channel would be:

Number of points = 2^(1) = 2 points.
