Conversion of Analog to Digital Signals
Conversion of analog signals to digital signals can be done using one of these methods. You can look here for a detailed understanding.
- Pulse Code Modulation: This is the most generic method used for converting analog signal to digital signal. The method includes sampling the given analog data, quantization of sampled values, and then encoding the data into a form that can be transmitted.
- Delta Modulation: This technique is used since pulse code modulation is a complex method. This technique uses a modulator which uses a comparator and has a delay unit. The demodulator is further used to extract the original signal.
- Adaptive Delta Modulation: This technique is an improvement in the delta modulation technique. The technique manages to change the step size depending on the modulator and the message signal. There is less data loss in this method.

Signals and Systems
Electronics and communication engineering deals with signal processing and signal transmission. This field of engineering is known as signals and systems. In this article, we will introduce the readers to signals and systems by defining all the necessary terms and discussing the components that make up the communication system.
We will also categorize signals and systems based on their classification and try to understand them through circuit diagrams. The later part of the article will talk about the characteristics, advantages, and applications of signals and systems along with some limitations. The article will conclude with some frequently asked questions that the readers can refer to.
