Physics Quiz: Interference And System Capacity

What is frequency interference?

• Complete silence of signals

• Enhancement of signals

• Increase in signal strength

• Distortion or disruption of signals

How is bandwidth capacity related to data transmission?

• Bandwidth capacity decreases data transmission speed

• Bandwidth capacity determines the amount of data that can be transmitted in a given amount of time.

• Bandwidth capacity is unrelated to data transmission

• Bandwidth capacity is only related to the size of the data being transmitted

What is signal-to-noise ratio and why is it important in wireless communication?

• Ratio of signal power to distortion power; It is important for determining the quantity of the signal received and the overall performance of the communication system.

• Ratio of signal power to noise power; It is important for determining the quality of the signal received and the overall performance of the communication system.

• Ratio of signal power to interference power; It is important for determining the quantity of the signal received and the overall performance of the communication system.

• Ratio of noise power to signal power; It is important for determining the quality of the signal received and the overall performance of the communication system.

Explain the concept of channel allocation in wireless communication.

• Allowing all devices to use the same frequency band

• Assigning specific frequency bands or channels to different users or devices to avoid interference and maximize system capacity.

• Sending data through physical cables

• Using different colors for data transmission

How is the wireless spectrum utilized in communication systems?

• By allocating different frequency bands for different types of communication.

• By using the same frequency band for all types of communication

• By not using any frequency bands at all

• By using only one frequency band for all types of communication
