1 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

2 Determine the number of M value and number of data bits that can be represented using FSK where the possible amplitude values are {0 Hz, 60 Hz}.

		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

3 Determine the number of M value and number of data bits that can be represented using ASK where the possible amplitude values are {0v, +1v, +2v, +3v, +4v, +5v, +6v, +7v}.

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

4 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

5 Select the true statement regarding the relationship between data rate (bit rate) and baud rate.

		a. data rate is the same as baud rate
		b. data rate is not dependent upon M (i.e., number of values that a symbol can take on)
		c. data rate can be equal to or greater than baud rate depending upon the value of M
		d. data rate is always less than baud rate

6 Electrical, electromagnetic, and optical symbols are used to represent logical (0s and 1s) data. As such, symbol rate is always equal to data rate, and the two terms can be used interchangeably. True / False

7 Unlike analog communications, digital communications do not involve the use of sinusoidal carriers during the digital modulation process. True/False
