Weekly Schedule

1) 1. Learns the development of digital communication. • Basics of digital communication, telegraph communications had developed since the moments. • Telegraph, telephone, radio, television, fax and computer communication tools such as numerical examples to show how it is used for communication of information. 2. Draw a simple block diagram of a digital communication and explain .
2) 3. Explain the advantages and disadvantages of digital communication direction. • Against Noise Sensitivity • Information carrying capacity • Performance • Measurement and evaluation • Error detection and correction • Communication privacy • The power system expenditures, etc.. aspects of digital communication systems, analog communication systems understand the comparison.
3) 4. Sampling theorem explains, how the sampled signal is applied. • understand how to do sampling. • Knowledge of the signal with a sampling frequency based on bandwidth (frequency) should establish a relationship between the moments
4) The minimum sampling frequency bandwidth of the signal must be at least twice to understand.

8) 3. Pulse position (place) modulation and the time it makes the application. • Pulse Position Modulation Draws the block diagram and explain. • When an input signal with a frequency according to sampling month as graphical displays. • The sampled amplitude shock proportional in amplitude and width as hard blows to produce graphical displays in phases. • PPM signal and the information produced to explain the relationship between signals. • In light of this information makes the PPM experiments and analyze the results on the oscilloscope.
9) 1. TDM (time division multiplexing) system requirements and explains their working principles. • Two-input of a TDM system required by a modulation in the transmitter and receiver block diagram to explain the draw and work. • TDM system can be applied to any digital modulation are explained with examples given. • carrying digital information, bit rate and sampling frequency of the line and the TDM system, including establishing the relationship between the information signal. • For more than two-port TDM system makes generalizations. • In light of this information makes the TDM test, analyze and interpret the results.
10) 1. Pulse Code Modulation (PCM), analog information, digital signal indicates the level of 0 to 1, and learns how to translate. • PCM modulation and demodulation, and draw diagrams to explain. • Quantization (Roll-up) and explains how to do the encoding process. • The number of bits used to establish a relationship between the quantization error. 2. Comply with the conditions required for a PCM system is designed. • Quantization effects of noise on the performance of the system to analyze. • Kuantalayıcı bits, based on the information signal bandwidth and sampling frequency bandwidth of the transmission
11) 3. The PCM system using variable-step kuantalayıcı learns the principles of the study. • analyze the dynamic nature of speech signals. • Compression and expansion of the principles and techniques of their time to contribute comments to the PCM system performance. • Understands how to use a type of compression curves. • A knowledge of the analytical signal compression curve as type A and the digital signal via PCM turns. • Differential PCM will learn the principles.
12) 4. Delta Modulation (DM), the analog information, digital signal indicates the level of 0 to 1, and learns how to translate. • DM modulation and demodulation, and draw diagrams to explain. • Two-level (+ -?) Sharply limiting the use of an analog signal is converted into digital signal. • "Pitch limit the concept of" moments. With this restriction, and sampling frequency? establishes a relationship between the steps. • More than two-level (adaptive DM) DM learns the principles. • make comparisons between the DM and PCM.
13) 1. RZ code with digital communication, NRZ, AMI, etc. Miller. lines of code and understand the different features. • Lines of code are needed to explain why. • Data of the "first" and "0" change to the draw against all codes, the study explains. • Edge detection method for providing synchronization with the transceiver, is emphasize the importance of line code. • Incorrect information against transmission lines indicates the importance of using the code.
