In this post I will comprehensively explain what logic gates are and its working. We will be taking a look at the basic definition, symbol, truth table, Multi input gates, we will be also constructing transistor based gate equivalents and finally we will take an overview on various relevant CMOS ICs. What are Logic Gates […]

Learning Basic Arduino Programming – Tutorial for the Newcomers
In this tutorial I have explained how to do basic Arduino programming through example codes and sample programs. This tutorial can be an extremely valuable course for all the newcomers who wish to grasp the basics through easy, understandable language. Introduction According to wikipedia a microcontroller is equivalent to a mini computer built inside a […]
Cathode Ray Oscilloscopes – Working and Operational Details
In this post I will elaborately explain how Cathode Ray Oscilloscopes (CRO) work and its internal construction. We will also learn how to use a CRO using the various controls and understand the graphical representations of the various input signals on the display screen of the scope. Importance of Cathode Ray Oscilloscopes (CRO) We know that majority […]
Transistor Common Collector
A BJT common collector amplifier is a circuit in which the collector and the base of the BJT share a common input supply, hence the name common collector. In our previous articles we have learned the other two transistor configurations, namely the common-base and the common-emitter. In this article I have explained the third and […]
How to Troubleshoot Transistor (BJT) Circuits Correctly
Troubleshooting BJT circuits is basically a process of identifying the electrical faults in the network using multimeters across the various nodes in the circuit. BJT troubleshooting techniques is a huge topic and therefore including 100 % solutions and strategies can be perhaps difficult within a single article. Basically, the user should know about a handful […]
Learning Basics of Semiconductors
In this post I will comprehensively explain regarding the fundamental working principles of semiconductor devices, and how the internal structure of semiconductors function under the influence of electricity. The resistivity value between these semiconductor materials neither has a complete conductor characteristic nor a complete insulator, it is in between these two limits. This feature may […]
