Time Base Generator
It has been mentioned earlier that the time domain oscilloscopes require a sweep generator that is linear with time for

Cathode Ray Tube Deflection System
This Post Deflection system of CRT is a continuation of my previous post Electron Gun of CRT. This post completely covers the
Capacitively Coupled Multistage Transistor Amplifier
Two or more amplifiers can be connected in a cascaded arrangement with the output of one amplifier driving the input
Transistor Amplifier Working Principle
A linear amplifier provides amplification of a signal without any distortion so that the output signal is an exact amplified
Bridge Rectifier Working Animation
What is Rectifier? A rectifier is a device that simply converts alternating current (AC) into direct current (DC). The way
Different Types of Diodes
Types of Diodes: Small signal or Small current diode – These diodes assumes that the operating point is not affected
Summary Of Transistor Bias Circuits
In figures below, npn transistors are shown. Supply voltage polarities are reversed for pnp transistors.
Methods of Transistor Biasing
In the interest of simplicity and economy, it is desirable that transistor circuit should have a single source of supply—the
Transistor Stabilisation
The collector current in a transistor changes rapidly when (i) the temperature changes, (ii) the transistor is replaced by another
