Chapter 11 : Optimal Reception of Digital Signal

1	In the phrase integration and dump, does the term dump refers to abrupt discharge of a capacitor?
	A)	Yes
	B)	No
2	In integration and dump receiver, the integration process enhances signal energy more than noise energy. Is the statement correct?
	A)	Yes
	B)	No
3	Maximum likelihood detector is an optimal detector in the sense of setting optimal decision threshold that gives minimum error probability. Is that true?
	A)	Yes
	B)	No
4	If prior probabilities are not equal then the decision threshold can be pushed towards higher probability conditional pdf than equal probable case to get lower probability of error. Is that correct?
	A)	Yes
	B)	No, can be pushed up to a particular value towards other direction to getlower probability of error
5	Does Schwartz inequality contain an equality condition useful for getting optimum filter relation?
	A)	Yes
	B)	No
6	Can a physically realizable filter have complex impulse response?
	A)	Yes
	B)	No
7	Is it true that in matched filter error probability depends on signal energy and not on wave shape?
	A)	Yes
	B)	No
8	Can matched filter and correlator give identical reception performances?
	A)	Yes
	B)	No
9	Is the bit probability of error for PSK same as that of QPSK?
	A)	Yes
	B)	No
10	Is the signal space one dimensional for BPSK signal?
	A)	Yes
	B)	No
11	In general, as M increases error probability for M-ary PSK increases while that of M-ary FSK decreases. Is the statement correct?
	A)	Yes
	B)	No
12	For a constant bit error rate, is it necessary to increase bit energy to noise ratio to reduce bandwidth requirement?
	A)	Yes
	B)	No
13	Does Shanon’s limit depend on probability of error?
	A)	Yes
	B)	No
