1.     What is communication?
Communication is the process of transferring information from one point to another.

2.     What is electronic communication?
Transmission of information using electronic devices and systems.

3.     What are the types of communication?

o   Analog communication

o   Digital communication

4.     What is modulation?
The process of varying a carrier signal according to the information signal.

5.     What is demodulation?
The process of extracting the original information from a modulated signal.

6.     What is amplitude modulation (AM)?
Modulation in which the amplitude of the carrier wave is varied according to the message signal.

7.     What is frequency modulation (FM)?
Modulation in which the frequency of the carrier wave is varied by the message signal.

8.     What is phase modulation (PM)?
Modulation in which the phase of the carrier signal is varied.

9.     What is a carrier wave?
A high-frequency signal used to carry the information signal.

10.  What is bandwidth?
The range of frequencies required to transmit a signal.

11.  What is noise?
Unwanted signals that interfere with communication.

12.  What is SNR (Signal-to-Noise Ratio)?
The ratio of signal power to noise power. Higher SNR means better communication quality.

13.  What is a transmitter?
A device that modulates and transmits signals.

14.  What is a receiver?
A device that receives and demodulates signals.

15.  What is a transducer?
A device that converts one form of energy into another, like microphone and speaker.

16.  What is pulse modulation?
Modulation technique where message signal is represented as pulses.

17.  What is sampling?
The process of converting a continuous-time signal into a discrete-time signal.

18.  What is Nyquist theorem?
Sampling rate must be at least twice the highest frequency of the signal to avoid distortion.

19.  What is TDM (Time Division Multiplexing)?
Multiple signals are transmitted over the same channel by dividing time slots.

20.  What is FDM (Frequency Division Multiplexing)?
Multiple signals are transmitted simultaneously using different frequency bands.

21.  What is ASK (Amplitude Shift Keying)?
A digital modulation technique where amplitude represents binary data.

22.  What is FSK (Frequency Shift Keying)?
A digital modulation technique where frequency represents binary data.

23.  What is PSK (Phase Shift Keying)?
A digital modulation technique where phase represents binary data.

24.  What is a repeater?
A device used to regenerate and extend signals over long distances.

25.  What is antenna?
A device used for transmitting and receiving electromagnetic waves.

26.  What is modulation index?
The measure of the extent of modulation in a carrier signal.

27.  What is baseband signal?
The original low-frequency information signal before modulation.

28.  What is channel capacity?
The maximum rate of data transfer through a communication channel.

29.  What are applications of electronic communication?

• Telecommunication
• Radio and TV broadcasting
• Satellite communication
• Mobile communication

30.  Why is modulation necessary?

• To reduce antenna size
• To avoid signal interference
• To increase transmission range
