Designing Op amp Oscillators

In this post we learn how to design opamp based oscillators, and regarding the many critical factors required for generating a stable oscillator design. Op amp based oscillators are normally used to generate precise, periodic waveforms like square, sawtooth, triangular, and sinusoidal. Generally they operate using a single active device, or a lamp, or a … Read moreDesigning Op amp Oscillators

How Cathode Ray Oscilloscopes (CRO) Work

solved example problem CRO

In this post we will elaborately discuss 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 … Read moreHow Cathode Ray Oscilloscopes (CRO) Work

UP DOWN Logic Sequence Controller Circuit

Using a set of latch/reset networks it becomes possible to allow a logic to move in a forward sequence, switching ON a given set of outputs HIGH, in response to an alternating input clock. And once the max limit is reached, the input clocks begin shutting down or withdrawing the sequence in the opposite order. … Read moreUP DOWN Logic Sequence Controller Circuit

How to Connect Transistors (BJT) and Mosfet with Arduino

In this article we elaborately discuss the correct methods of using or connecting transistors like BJTs and mosfets with any microcontroller or an Arduino. No matter how well programmed or coded your Arduino may be, if it’s not correctly integrated with a transistor or an external hardware, could result in inefficient operation of the system … Read moreHow to Connect Transistors (BJT) and Mosfet with Arduino

Understanding Amplifier Circuits

In general, an amplifier can be defined as a circuit designed to boost an applied low power input signal into a high power output signal, as per the specified rating of the components. Although, the basic function remains the same, amplifiers could be classified into different categories depending on their design and configurations. Circuits for … Read moreUnderstanding Amplifier Circuits
