Question

Module 2 - Quiz 2 TRUE OR FALSE T F 1. Only digital signals can be used to convey information in the communications environment, T F 2. The greater the bandwidth of the signal the greater its information carrying capacity T F 3. The transmission media that are used to convey information can be classified as guided or unguided. T F 4. Twisted pair may only be used to transmit analog and digital signals. T F S. Both analog and digital information can be encoded as either analog or digital signals. T F 6. In general, the equipment for encoding digital data into a digital signal is more complex and expensive than digital to analog modulation equipment. T F 7. Regardless of the design of the transmission system, there will be errors, resulting in the change of one or more bits in a transmitted block of data. T F 8. Redundant bits are not used by the receiver for error detection T F 9. Synchronization and interfacing techniques are sufficient by themselves T F 10. The receiver must be able to distinguish control information from the data being transmitted. T F 11. Multiplexing allows several transmission sources to share a larger transmission capacity T F 12. With time division multiplexing, modulation equipment is needed to move each signal to the required frequency band and multiplexing equipment is needed to combine the modulated signals. T F 13. Circuit switching is the basis for private networks built on leased lines and using on site circuit switches. T F digital data 14. Circuit switching is very efficient in handling

Answer 1

Solution

Explanation

Not only digital signals can be used to convert information in the communication environment but also analog signals also used
Hence Answer is False
---
Twisted pair may only be used to transmit analog and digital signals
coaxial cables , fiber optics can be also used
Hence Answer is False
----
Equipment for encoding digital data into a digital signal is less complex and less expensive than digital-to-analog equipment
Hence Answer is False
---
Synchronization and interfacing techniques are not sufficient . It is necessary to have a layer of control in each communicating device that provides certain functions
Hence Answer is False
