Question 2: What is the primary advantage of using a differential amplifier in RF circuit design?

Which action should you take?

Choose only one option

It improves noise immunity and provides better signal integrity

It reduces the number of components required

It provides higher gain at lower frequencies

It increases the power consumption of the circuit

Question 3: What is the impact of improper PCB grounding on EMC performance?

Which action should you take?

Choose only one option

Increased EMI susceptibility

Reduced signal propagation

Question 5: What is the role of beamforming in modern wireless communication systems?

Which action should you take?

Choose only one option

To direct signals toward specific devices, improving signal strength and reducing interference

To reduce the bandwidth usage of the communication channel

To increase the range of the wireless signal by amplifying power

To filter out unwanted frequencies from the signal

Question 6: In an RF communication system, what is the effect of using a band-pass filter in the receiver?

Which action should you take?

Choose only one option

It minimizes the effect of noise on the signal

It reduces the power consumption of the receiver

It amplifies the signal across all frequencies

It allows signals within a specific frequency range to pass while attenuating signals outside that range
