Communication engineering is the study and application of techniques for designing, analyzing, and optimizing systems and networks that transmit information.
What are the key components of a communication system?
The key components of a communication system are the transmitter, the channel, and the receiver.
What is modulation?
Modulation is the process of modifying a signal in order to encode information onto it for transmission.
What is the Nyquist-Shannon sampling theorem?
The Nyquist-Shannon sampling theorem is a fundamental result in the field of signal processing which states that a continuous signal can be perfectly reconstructed from samples taken at a rate twice that of its highest frequency component.
What is channel coding?
Channel coding is the process of adding redundancy to a signal prior to transmission to enable recovery of the original signal in the presence of channel noise or interference.
What is digital signal processing?
Digital signal processing is the study and application of algorithms for processing signals, including filtering, compression, and analysis.
What is multiplexing?
Multiplexing is the process of combining multiple signals onto a single transmission medium.
What is a codec?
A codec is an algorithm for encoding and decoding digital data, especially audio and video data.
What is a demodulator?
A demodulator is a device that extracts the original signal from a modulated carrier signal.
What is a bandpass filter?
A bandpass filter is a type of filter that allows only signals with frequencies within a certain range to pass through.
What is frequency hopping?
Frequency hopping is a technique used in wireless communication systems in which the frequency of the carrier signal is rapidly switched between different frequencies to improve resistance to interference and jamming.
What is amplitude modulation?
Amplitude modulation is a modulation technique in which the amplitude of a carrier signal is varied in proportion to the amplitude of the modulating signal.
What is frequency modulation?
Frequency modulation is a modulation technique in which the frequency of a carrier signal is varied in proportion to the amplitude of the modulating signal.
What is phase modulation?
Phase modulation is a modulation technique in which the phase of a carrier signal is varied in proportion to the amplitude of the modulating signal.
What is spread spectrum?
Spread spectrum is a technique used in wireless communication systems in which a signal is intentionally spread over a wide frequency band to reduce interference and increase security.
