QUESTION 22 Which of the followings is true? Given an RC circuit, O A. the circuit has a negative exponential magnitude response. OB. All of the given options. O C. the circuit is first-order. O D. the circuit has one energy-storage element. QUESTION 23 Which of the followings is true? Frequency-coupling components should be filtered out because O A. they represent low-frequency components which mostly do not carry useful information. B. they represent low-frequency components which mostly carry useful information. O C. they represent high-frequency components which mostly carry useful information. D. they represent high-frequency components which mostly do not carry useful information. QUESTION 24 Which of the followings is true? For SSB modulation, O A. a phase shifter is necessary but it is not always required. O B. its generation appears to be as complicated as DSB generation. OC. a phase shifter can be practically omitted. O D. a phase shifter must be deployed.
