by Tarun Agarwal 6 years ago Types of Electric Actuators and Its Applications The actuator is a mechanical or electro-mechanical device which is used to offer controlled, positioning and sometimes limited movements which are functioned manually, electrically, or by a variety of fluids like air, hydraulic, etc. The...
by Tarun Agarwal 6 years ago Electronic Learning Kit using 15 Projects-in-1 The designing process of the electronic learning kits in the early days can be done by fitting required components and copper wires to a wooden board and soldered to them. In some cases a circuit diagram was first drawn on a plain paper...
by Tarun Agarwal 7 years ago Stereo Amplifier Circuit using TDA2822 IC TDA2822 is one kind of Op-amp (operational amplifier) that can be used in low output applications like a stereo amplifier. This IC has some features like it is available in 16-pin power DIP package, low crossover distortion, low-quiescent...
by Tarun Agarwal 7 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 7 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,...
