True

False

10 points   

QUESTION 2

1. A signal’s effective bandwidth is smaller than its absolute bandwidth.

True

False

10 points   

QUESTION 3

1. What is the second harmonic frequency of a fundamental frequency, f=100kHz?

		a. 50kHz
		b. 100kHz
		c. 200kHz
		d. 200MHz

Answer 1

Question 1

True

Signal that represents information will be associated with both fundamental and harmonic frequencies.

Fundamental is the basic or original wave form of the harmonic frequency

Question 2

effective bandwidth is smaller than the absolute band width because the absolute bandwidth increases with respect to center frequency of the signal so the answer is true

Question 3

If fundamental frequency is x then the second harmonic is 2x and third is 3x so

Here fundamental frequency is 100 kHz

So second harmonic frequency is 100*2 =200kHz
