by Tarun Agarwal 9 years ago LM340 Series Voltage Regulators A voltage regulator is one of the most commonly used electronic circuitry in any device. A synchronized voltage (without fluctuations & noise levels) is very significant for the smooth functioning of many digital electronic devices....
by Tarun Agarwal 9 years ago Digital Electronics: Flip-Flops Tutorial The term flip-flop (FF) was invented in the year 1918 by the British physicist F.W Jordan and William Eccles. It was named as the Eccles Jordan trigger circuit and includes two active elements. The design of the FF was used in the British...
by Tarun Agarwal 9 years ago Phase Locked Loop Working with Applications The phase-locked loop is one of the basic blocks in modern electronic systems. It is generally used in multimedia, communication and in many other applications. There are two different types of PLL’s – linear and nonlinear. The nonlinear...
by Tarun Agarwal 9 years ago Zero Crossing Detector Circuit and Working A zero-crossing detector or ZCD is one type of voltage comparator, used to detect a sine waveform transition from positive and negative, that coincides when the i/p crosses the zero voltage condition. In this article, we discuss the zero-crossing...
by Tarun Agarwal 9 years ago LCD Interfacing with 8051 Microcontroller A decade back the process and control operations were implemented by using the microprocessor only. But nowadays the situation is changed and it is occupied by a new device called Microcontroller. We can’t find any electronic gadget...
by Tarun Agarwal 9 years ago Sawtooth Wave Generator and its Working Principle A waveform is a shape that represents changes in amplitude with respect to time. A periodic waveform includes a sine wave, square wave, triangular wave, sawtooth wave. On the x-axis, it indicates the time and on the y-axis it indicates...
by Tarun Agarwal 9 years ago Different Types of Voltage Regulators with Working Principle In the power supply, voltage regulators play a key role. So before going to discuss a voltage regulator, we have to know that what is the role of a power supply while designing a system?. For instance, in any working system like a smartphone,...
by Tarun Agarwal 9 years ago What is a Half Wave Rectifier : Circuit & Its Characteristics In the period 1880’s itself, the identification and uniqueness of rectifiers were started. The advancement of rectifiers has invented various approaches in the domain of power electronics. The initial diode which was employed in the rectifier...
by Tarun Agarwal 9 years ago Heat Sensor Circuit and Working Operation The main property of a heat sensor is to sense the heat, which is present around the sensor. When the set value of the temperature is high, then it is indicated with the help of a glowing LED. The usage of the heat sensor circuit is inside...
by Tarun Agarwal 9 years ago Understanding about the P-N Junction Diode Theory and Working A P-N Junction Diode is formed by doping one side of a piece of silicon with a P-type dopant (Boran) and the other side with a N-type dopant (phosphorus).Ge can be used instead of Silicon. The P-N junction diode is a two-terminal device....
