by Tarun Agarwal 1 year ago Class A Amplifier Circuit Working and Applications We have already discussed, the classes and classifications of power amplifiers in our earlier articles. The power amplifier circuits are used to deliver high power to drive the loads likes loudspeakers. The power amplifiers are classified...
by Tarun Agarwal 1 year ago Difference Between PAM, PWM and PPM In a communication system, the modulation is an important step. Modulation is the process of transmitting a message signal (Baseband signal with low frequency) from transmitter to receiver without changing its characteristics (like amplitude,...
by Tarun Agarwal 2 years ago About Multiple Input Multiple Output (MIMO) Technology MIMO is abbreviated as Multiple-input multiple-output. This is a wireless radio communication and multi-path technology that is being mentioned and used in many new technologies these days. This technique has been developed for enhancing...
by Tarun Agarwal 2 years ago Armstrong Oscillator Circuit Working and Application An Armstrong oscillator, Colpitts, Clapp, Hartley, and crystal-controlled oscillators are several types of resonant LC feedback oscillators (LC electronic oscillator). An Armstrong oscillator (also known as Meissner oscillator) is actually...
by Tarun Agarwal 2 years ago Optical Sensor Basics and Applications An optical sensor converts light rays into an electronic signal. The purpose of an optical sensor is to measure a physical quantity of light and, depending on the type of sensor, then translates it into a form that is readable by an integrated...
by Tarun Agarwal 2 years ago Wireless Sensor Network Architecture and Its Applications Currently, WSN (Wireless Sensor Network) is the most standard services employed in commercial and industrial applications, because of its technical development in a processor, communication, and low-power usage of embedded computing devices....
by Tarun Agarwal 3 years ago Tutorial on How Mobile Phone Jammer Works The GSM mobile jammer is a device which transmits the signals to the same frequency. The jamming section is successful when the area of the mobile phone signal is disabled if the jammer is on. The first jamming device was developed and...
by Tarun Agarwal 3 years ago Bluetooth Protocol – Type, Data Exchange and Security The first Bluetooth was developed in the year 1994 by Sven Mattison and Jaap Haartsen. They were working in a mobile phone company named Ericsson which is in Sweden. Then five companies came forward and joined to form the Bluetooth special...
by Tarun Agarwal 3 years ago Wireless Home Automation using IOT The process of controlling or operating various equipment, machinery, industrial processes, and other applications using various control systems and also with less or no human intervention is termed as automation.
