While the conversion of an analog signal into a binary signal, the PCM (pulse code modulation) technique is used. But this system has a disadvantage like it requires large bandwidth because all the bits are going to be transmitted and there is a difference between the analog signal and the digital signal. So these can be overcome by using Delta modulation. It is one type of technique used for the conversion of an analog signal into a digital version. The definition of delta Modulation is the … [Read more...]
What is Amplitude Modulation – Derivatives, Types and Benefits
Initially, the birth of amplitude modulation starts by considering a continuous spark transmission and placing a carbon microphone in the antenna lead. This type of positioning has created sound waves, and these got varied both with the intensity and resistance over the transmission. Even there was a disturbing noise, signals can be heard over a distance and that’s up to some hundred meters. So, the introduction of uninterrupted sine signals allowed for continuous transmission and then on AM w … [Read more...]
What is an Attenuator : Design, Types & Its Applications
Electricity, communication, entertainment, utility resources (gas), etc. everything is required to be transmitted from one point to another. For transmitting these, there are different type of technologies and transmitting techniques. Electrical power generated at one place is transmitted to consumer point using transmission lines along with required substations. For transmitting power from one point to another point, amplifiers are used to increase the power of signal and are called as … [Read more...]
An Overview on the Concept of Frequency Modulation
Amplitude Modulation is not only the approach of modulating the signal, but there also exist many other kinds of modulation techniques. Frequency Modulation is one of the types of modulation. In the earlier days of communications, the necessary bandwidth for transmission of signals was not wide and even they do not hold the ability to reduce the interference signals. In such a scenario, frequency modulation was introduced but it was not much accurate compare with amplitude modulation. Then … [Read more...]
Cluster Computing : Architecture & Its Types
Earlier computing features were good to solve simple problems, but they have no ability to sync up the current day technologies and advancements. Pricing scenarios, low performance, reliability and some of the other reasons couldn’t gain access to manage huge data and previous computing systems can’t clear today’s IT problems. In the scope of this, IT departments introduced an innovative approach in solving the limitations of a single system and that was “Cluster Computing”. The advantages of thi … [Read more...]
Basics of UART Communication
Communication plays a significant role in transferring information from one end to another end (source to destination). In this digital landscape where most of the day-to-day tasks are completed through portable devices, communicating the data effectively by utilizing conventional resources is a crucial task. Moreover, with the existence of myriad modes of communication devices and embedded platforms in a single architecture, transferring data without any disturbance or noise in the signal is a … [Read more...]
What is Modulation? Different Types of Modulation Techniques
Communication is the basic attraction of mankind as it gives the knowledge of what is going on around us. In our daily life, we communicate with many people and use the entertainment media like television, radio, internet and newspaper to get ourselves involved. These entertainment media act as a source of communication. Electronic communication comprises TV, radio, internet, etc. When we want to transmit a signal from one location to another, we have to strengthen the signal. After undergoing s … [Read more...]
