Digitally controlled oscillator
open-in-new
<p>A digitally controlled oscillator or DCO is used in <a href="/facts/Synthesizer/NrmdVrPa">synthesizers</a>, <a href="/facts/Microcontroller/MKrnAhnm">microcontrollers</a>, and <a href="/facts/Software-defined_radio/k7qLq1mu">software-defined radios</a>. The name is <a href="/facts/Analogy/LYcGaTdm">analogous</a> with "<a href="/facts/Voltage-controlled_oscillator/85sdYF0m">voltage-controlled oscillator</a>". DCOs were designed to overcome the tuning stability limitations of early VCO designs. </p>
