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 Deflection system of the CRT. When the electron beam is

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 of the next. Each amplifier in a cascaded arrangement is
Transistor Amplifier Working Principle
A linear amplifier provides amplification of a signal without any distortion so that the output signal is an exact amplified replica of the input signal. A voltage-divider biased transistor with
Bridge Rectifier Working Animation
What is Rectifier? A rectifier is a device that simply converts alternating current (AC) into direct current (DC). The way a rectifier changes AC to DC is by the use
Different Types of Diodes
Types of Diodes: Small signal or Small current diode – These diodes assumes that the operating point is not affected because the signal is small. Large signal diodes – The
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 one in the output circuit (i.e. VCC). The following are the
Transistor Stabilisation
The collector current in a transistor changes rapidly when (i) the temperature changes, (ii) the transistor is replaced by another of the same type. This is due to the inherent
Transistor Collector Feedback Bias
In Figure, the base resistor RB is connected to the collector rather than to VCC, as it was in the base bias arrangement discussed earlier. The collector voltage provides the bias for
