Oscillators: An Overview of Their Role in Electronic Circuits

08/06/2023


Crystal oscillators are electronic circuits designed to generate an electrical signal of a precise frequency. This frequency is determined by the physical characteristics of a quartz crystal, which serves as the oscillator's resonant element. This guide will look to further explain the basics of oscillators, the magic they spin in generating frequencies, and the critical role they play in electronic circuits.

Understanding Frequency Tolerance and Stability in Quartz Crystals and Oscillators
