QUESTION 6
Determine the number of M value and number of data bits that can be represented using PSK where the possible amplitude values are {0, /8, /4, /2}.
a. M=2, N=1 bit per symbol
b. M=4, N=2 bit per symbol
c. M=6, N=3 bit per symbol
d. M=8, N=3 bit per symbol
QUESTION 7
QAM (quadrature amplitude modulation) incorporates both ASK and FSK techniques.
True
False
QUESTION 8
When using ASK, FSK or PSK techniques, how can we increase data rate?
a. by decreasing "M" value
b. Hartleys Law tells us that baud rate will always equal data rate when using ASK, FSK or PSK
c. by increasing M, we can increase the data rate when compared to the baud rate
d. by increasing M, we can increase the baud rate when compared to the data rate
QUESTION 9
Determine the data rate possible given 32-QAM modulation where M=32, and baud rate is 9.6 kbps.
a. 4.8 kbps
b. 48 kbps
c. 14.4 kbps
d. 1.44 kbps
QUESTION 10
QPSK is the same as QAM. Both can be used interchangeably.
True
False
