CPE 313 QUIZ 1

___________ is the transmission and reception of sound processed into patterns of numbers, or "digits"

• Digital Processing

• Digital communication

• Digital Radio

• Digital Transmission

________ is the transmission of signals that vary discretely with time between two        values of some physical quantity, one value representing the binary number 0 and the other representing

• Digital Processing

• Digital communication

• Digital Radio

• Digital Transmission

 The source of information can be analog or digital, e.g. analog: audio or video signal, digital: like teletype signal

• Source Decoder

• Source Encoder

• Channel Encoder

• Information Source

The process of efficiently converting the output of whether analog or digital source into a sequence of binary digits is known as __________.

• Source Decoder

• Source Encoder

• Channel Encoder

• Information Source

It Introduce in controlled manner, some redundancy in the binary information sequence that can be used at the receiver to overcome the effects of noise and interference encountered in the transmission on the signal through the channel.

• Source Decoder

• Source Encoder

• Channel Encoder

• Information Source

      If an analog signal is desired then source decoder tries to decode the sequence from the knowledge of the encoding algorithm. And which results in the approximate replica of the input at the transmitter end.

• Source Encoder

• Channel Encoder

• Information Source

It turns convert the sequence into electric signals so that we can transmit them on channel and maps the binary sequences into signal wave forms.

• Digital Modulator

• Channel Decoder

• Channel

• Digital Demodulator

It is the physical medium that is used for transmitting signals from transmitter to receiver.

• Digital Modulator

• Channel Decoder

• Channel

• Digital Demodulator

The processes that the channel corrupted transmitted waveform and reduces the waveform to the sequence of numbers that represents estimates of the transmitted data symbols.

• Digital Modulator

• Channel Decoder

• Channel

• Digital Demodulator

    It attempts to reconstruct the original information sequence from the knowledge of the code used by the channel encoder and the redundancy contained in the received data
