Objectives

In this chapter we will explore the working principle of the oscillator. Generally speaking, the oscillator produces sinusoidal and other waveforms. Beginning with a detailed circuit analysis of the oscillator, we will proceed to discuss the conditions and frequency of oscillation. Following this, the different types of oscillators—Tuned oscillator, Hartley oscillator, Colpitts oscillator, Clapp oscillator, Phase-shift oscillator, Crystal oscillator and Wien-bridge oscillator—will ...

Head of Cybersecurity

I wanted to learn C and C++, but it didn't click for me until I picked up an O'Reilly book. When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.

Addison B.

Field Engineer

I’ve been on the O’Reilly platform for more than eight years. I use a couple of learning platforms, but I'm on O'Reilly more than anybody else. When you're there, you start learning. I'm never disappointed.

Amir M.

Data Platform Tech Lead

I'm always learning. So when I got on to O'Reilly, I was like a kid in a candy store. There are playlists. There are answers. There's on-demand training. It's worth its weight in gold, in terms of what it allows me to do.
