by Tarun Agarwal 5 years ago NFC Sensor Working and Its Applications The term NFC stands for “Near Field Communication”. At present it is growing very fast in various smartphones, however, it works internally within the mobile phone. But we don’t know about its working. Nowadays, it is mainly using...
by Tarun Agarwal 5 years ago Basics of Optical Transmitters and Receivers with Specifications At present, the growth in information technology has increased using the current telecommunication systems. Mostly, OFC (optical fiber communication) plays an essential role in the telecommunication system development with a high speed...
by Tarun Agarwal 5 years ago Adaptive Delta Modulation – Block Diagram and Applications In communication systems, the modulation methods are used to transmit signals over long distances. In the modulation process, the properties of a high-frequency signal such as amplitude, phase, etc… are changed according to the low-frequency...
by Tarun Agarwal 5 years ago Delta Modulation With It’s Block Diagram When signals are transmitted over long distances, they get affected by noise and interference. There are several methods invented for effective transmission of signals over long distances without any error. The conversion of analog signals...
by Tarun Agarwal 5 years ago Frequency Shift Keying (FSK) Working & Applications The frequency shift keying is the most important digital modulation technique, and it is also known as FSK. A signal has the amplitude, frequency, and phase as properties. Every signal has these three properties. To increase any one of...
by Tarun Agarwal 5 years ago Amplitude Shift Keying (ASK) Working and Applications The most important and interesting concept in communication is Modulation. It has different types. Modulation is defined as the improving the signal characteristics amplitude, frequency or phase with reference of the carrier signal. If...
by Tarun Agarwal 5 years ago Phase Shift Keying (PSK) : Types and Its Applications The term PSK or Phase shift keying is broadly used in a radio communication system. This kind of technique is mostly compatible with data communications. It allows information in a more efficient way to be carried over a radio communications...
by Tarun Agarwal 5 years ago Antenna Gain – Directivity, Efficiency and Its Conversion Antennas are used in this modern communication for transmitting the data and receiving the data through a wired channel or wireless channel. Or in another way, it can be defined as transmitting and receiving the radio waves in all horizontal...
by Tarun Agarwal 5 years ago What is Attenuation : Different Types & Its Causes The attenuation is a telecommunication word which refers to reduction within signal strength. This can occur while transmitting signals over lengthy distances. It can be calculated in dB (decibels) in terms of voltage. The function of this...
by Tarun Agarwal 5 years ago AT Commands Tutorial The controlling of a MODEM can be done by using instructions or AT commands. Here term AT in the command is the short form of an Attention. The command line used in every modem starts with ‘AT’ otherwise ‘at’ so these commands are...
