| Question 320 |
A digital signaling system is required to operate at 9600 bps. If a signal element encodes a 4-bit
word, what is the minimum required bandwidth of the channel?
word, what is the minimum required bandwidth of the channel?
| 1200Hz | |
| 4800Hz | |
| 19200Hz | |
| 1900Hz |
Question 320 Explanation:
Using Nyquist’s equation: C = 2B log2M
We have C = 9600 bps a. log2M = 4, because a signal element encodes a 4-bit word Therefore,
C = 9600 = 2B x 4, and B = 1200 Hz
We have C = 9600 bps a. log2M = 4, because a signal element encodes a 4-bit word Therefore,
C = 9600 = 2B x 4, and B = 1200 Hz
