Digital Comm 1

It converts a physical signal from an information source into an electrical signal that can be processed and transmitted.

• modulator

• output transducer

• input transducer

• encoder

It compresses the data into minimum number of bits.

• source encoder

• transducer

• communication channel

• channel encoder

It maps binary information (0s and 1s) into signal waveforms suitable for transmission through a communication medium.

• source encoder

• digital demodulator

• channel encoder

• digital modulator

The physical or logical pathway that allows the transmission of signals from the transmitter end to the receiver end.

• transducer

• encoder

• demodulator

• channel

It converts the analog signal back into a digital format, ideally restoring the original binary data.

• output transducer

• digital demodulator

• channel decoder

• source decoder

It removes the carrier signal and reverses the process of modulation.

• output transducer

• digital demodulator

• channel decoder

• source decoder

It converts the signal into the original physical form.

What type of communication channel is shown in the picture?

• UTP cable

• STP cable

• Fiber optic cable

• Coaxial cable

It includes assigning a specific numerical value to represent the amplitude of the signal at that moment. This process converts the continuous amplitude values into discrete values.

• Encoding

• Quantization

• Sampling

• Modulation

This includes transforming the quantized values into binary code.
