So here we are talking about controlling lamps, motors, heaters and other similar loads using devices like thyristor and triac, right? Both these devices, thyristor and triac can actually do this job like switch ON/OFF or adjust power for these loads. But then we must know one big issue when we try to use thyristor […]

Explained: Class AB Amplifier Circuits
So both Class B amplifier and Class AB amplifier types are having this special output stage which we call push-pull type right? And in this output section we always got two power transistors or maybe sometimes two FETs also that are joined or arranged in one special manner so that these two can take the […]
What is Crossover Distortion in Class-B Amplifier Circuits
When we talk about distortion in an amplifier we are basically referring to how the output signal does not exactly match the original input signal it gets altered in some way. One particular type of distortion that affects amplifiers with a push-pull design is something known as crossover distortion. This happens specifically at the point […]
Understanding Distortion in Amplifier Circuits
In order for a signal amplifier to do its job properly and make sure that the output signal does not get distorted in any way it is really important to have some kind of DC Bias applied to its Base or Gate terminal. You see, a DC bias is necessary because it allows the amplifier […]
Explained: 7-Segment Display Counter Circuits
In today’s world showing numbers and letters on multiple LED displays is pretty simple, thanks to microcontrollers like Arduino or Raspberry Pi. With just a small piece of code we can easily display the digits we need. But as electronics students or hobbyists there are times when we need to show multiple numbers or digits […]
Understanding MOD Counters or Cascaded Counter Circuits
A counter mainly works by adding one to its value every time it gets a pulse from the clock signal. When a counter counts up in response to the clock, we say it is in “count-up” mode. If it counts down instead, we call that “count-down” mode. There are also special counters that can do […]
