Chapter 4 : Angle Modulation

1	Is frequency modulation a linear modulation?
	A)	Yes
	B)	No
2	Is it true that amplitude of transmitted carrier doesn’t carry any message information in phase modulation?
	A)	Yes
	B)	No
3	Is phase information obtained by differentiating frequency with time?
	A)	Yes
	B)	No, by integrating
4	In phasor representation of AM, length of carrier phasor is varied while in FM the angle is varied. Is it correct?
	A)	Yes
	B)	No
5	Narrowband PM with magnitude of modulating signal = 1 and AM have identical energy/power spectral density. Is that true?
	A)	Yes
	B)	No
6	Does a Gaussian modulating signal produce Gaussian power spectral density for wideband FM?
	A)	Yes
	B)	No
7	Is long term stability a major concern for parameter based FM generation?
	A)	Yes
	B)	No
8	Frequency multiplication is useful in increasing the deviation. Is it correct?
	A)	Yes
	B)	No
9	Does a frequency selective network generate only amplitude variation at its output?
	A)	Yes
	B)	No, both amplitude and frequency vary
10	Is it approximately possible to generate an FM signal which has frequency components only at one side of the carrier?
	A)	Yes
	B)	No
11	Stereophonic FM broadcast requires generation of sum and difference signals of left and right audio. Is that correct?
	A)	Yes
	B)	No
