It has been mentioned earlier that the time domain oscilloscopes require a sweep generator that is linear with time for…
This Post Deflection system of CRT is a continuation of my previous post Electron Gun of CRT. This post completely covers the…
Two or more amplifiers can be connected in a cascaded arrangement with the output of one amplifier driving the input…
A linear amplifier provides amplification of a signal without any distortion so that the output signal is an exact amplified…
What is Rectifier? A rectifier is a device that simply converts alternating current (AC) into direct current (DC). The way…
Types of Diodes: Small signal or Small current diode - These diodes assumes that the operating point is not affected…
In figures below, npn transistors are shown. Supply voltage polarities are reversed for pnp transistors.
In the interest of simplicity and economy, it is desirable that transistor circuit should have a single source of supply—the…
The collector current in a transistor changes rapidly when (i) the temperature changes, (ii) the transistor is replaced by another…
