In this lesson, we have learned about the difference between data and signal, composite signal, the bandwidth of periodic and nonperiodic composite signals

We have learned about the data communication, Data flow, composition of analog and digtal signals,periodic analog signals.

The Conclusions and Lessons we learned Data flow,Data and Signals,Wavelength and period,bandwidth of periodic and nonperiodic composite signals and Digital Signals.

In this lesson,we have learn about  Data flow,Data and signals ,comparison of analog and Digital signal,periodic analog signals.

We learnt deeply about data communication with data flow and signal and understood the basic difference between data and signal. Then we also learnt three components of a signal with its difference and understood characteristics of digital signal. 

This lesson, we learned about the difference between data and signal, the bandwidth, composite signal,etc.

In this lesson, we learned about the difference between data and signal,the bandwidth, composite signal,  and etc. 

In this lesson, we learn about  Data flow, Data, and signals, comparison, the difference between data and signal, composite signal, the bandwidth of periodic and nonperiodic composite signals, etc.

In this lesson,we have learn about  Data flow,Data and signals ,comparison of analog and Digital signal,periodic analog signals

In this lesson, we have learned about the data communication, Data flow, composition of analog and digital signals,periodic analog signals

We learn data flow  signal noise distortion attenuation

Thank You sir. 
i understand all the topic.

We learned Data flow,Data and Signals,Wavelength and period,bandwidth of periodic and nonperiodic composite signals and Digital Signals.

We also learned various types of line coding.
