Q:

Which among the following is not considered for detection of abnormal behaviour in power amplifier?

A) Temperature B) Transmitted power level
C) Received power level D) VSWR
 
Answer & Explanation Answer: C) Received power level

Explanation: Power amplifier is a part of RF front end section in transmit mode. It must be informed of transmit/receive mode to start and stop transmission. Transmitted power level, VSWR, and temperature are monitored for detection of abnormal behavour in power amplifier.

Q:

What is the parameter of analysis in reinforcement learning?

A) Number of requests during wake cycle B) Number of processes to achieve final outcome
C) Degree of failure D) Degree of success
 
Answer & Explanation Answer: D) Degree of success

Explanation: Reinforcement based learning assigns a weightage to an action on the basis of the degree of success of its outcome. When situations requiring similar action arise, the weightage associated with an action is analyzed for compatibility. The degree of success is computed by measuring the closeness of the obtained outcome with the expected outcome.

Q:

Which among the following options have forward error correction integrated into the demodulation process?

A) Trellis code modulation B) Soft decoding
C) Trellis code modulation and soft decoding D) Block codes
 
Answer & Explanation Answer: A) Trellis code modulation

Explanation: Forward error correction is carried out to reduce the number of bits received in error. It can be integrated into demodulation process such as in Trellis code modulation. It can be closely associated with demodulation process such as in soft decoding of convolution codes.

Q:

Interference with adjoining sectorized antennas can be avoided by _____

A) frequency nulling B) spatial nulling
C) spatial beam-forming D) frequency beam-forming
 
Answer & Explanation Answer: B) spatial nulling

Explanation: The interference with adjoining sectorized antenna can be avoided by the introduction of spatial nulls in the direction of nonsubscriber signal components. In high traffic intensity areas, nulls track subscribers that are on the same frequency and cancel their path movements.
