by Tarun Agarwal 8 years ago Designing of Counter Type ADC In electronics, the term “analog to digital conversion” can be denoted with ADC, A/D or A to D. It is one kind of system used to convert analog signal to digital signal. An A/D may also give an inaccessible dimension like an electronic...
by Tarun Agarwal 8 years ago Precision Rectifier using LT1078 When we think about rectifiers, the first thing that comes to our mind is power supplies, because rectifiers are used in power supply circuits. AC to DC conversion is mandatory in several circuits like high-precision signal processing circuits,...
by Tarun Agarwal 8 years ago Working of Automatic Fan Speed Control System using PIC16F877A Microcontroller The electric fan is one of the most essential electric devices of all time due to its benefits like cost effectiveness, low power consumption, etc. The electrical fan is a basic building block of several advanced technologies. These are...
by Tarun Agarwal 8 years ago Circuit Designing of Sample and Hold Circuit using Op-Amp In electronics, a sample and hold (S&H) circuit is an analog device that is used to take the voltage of a constantly changing analog signal and locks its value at a stable level for a particular least period of time. These circuits...
by Tarun Agarwal 8 years ago Schottky Barrier Rectifiers Working and Its Applications The Schottky diode or Schottky Barrier Rectifier is named after the German physicist “Walter H. Schottky”, is a semiconductor diode designed with a metal by the semiconductor junction. It has a low-forward voltage drop and a very rapid...
by Tarun Agarwal 8 years ago AC Power Controller with Programmable Interface The AC power can be controlled based on the working principle of firing angle control of thyristors. A display unit is used to display the full power and one can go through the preferred percentage to decrease the power to the load. Here,...
by Tarun Agarwal 8 years ago Circuit Diagram of 5V Buck Regulator using LM2678 There are many manufacturers of buck regulators with both synchronous and asynchronous switches. These regulators offer typical features like input voltage capacity, switching frequencies, and high-efficiency operation. With burst mode...
by Tarun Agarwal 8 years ago Different Types of Level Sensors and their Workings Liquid level sensors have been available in markets around for decades like food and drink, manufacturing, therapeutic and household, printing, and agriculture, automotive and white goods for leak recognition or level capacity. Some tool...
by Tarun Agarwal 8 years ago Bistable Multivibrator using 555 Timer Individual Sequential Logic circuits can be used to make complex circuits like Counters, Latches, Shift Registers, or Memories etc, but for these kinds of circuits to function in a “Sequential” way, they need the count of a...
by Tarun Agarwal 8 years ago Different Types of Rectifiers & Their Working In a large number of electrical and electronic circuits, DC voltage is required for its operation. We can simply alter the AC voltage into DC voltage by using a device called a PN junction diode. One of the most significant applications...
