किसी स्रोत से प्राप्त विद्युत संकेत अपने मूल रूप में उपयोग के योग्य नहीं होते हैं। उनमें तरह-तरह की कमियाँ होती हैं। जैसे संकेत का बहुत क्षीण होना या कम वोल्टेज का होना; संकेत में अत्यधिक शोर (नॉयज) होना आदि। अतः विद्युत [[संकेत|संकेतों]] को अधिक उपयोगी बनाने के लिये उन्हें अनेक प्रकार से परिवर्तित किया जाता है। इस क्रिया को <ref>{{webbref|url=http://dl.icdst.org/pdfs/files/d7c336c8cb6f02b42a1eae7a072f4092.pdf|titel=Introduction to Virtualization|år=2013|hämtdatum=2017-06-06|arkivurl=https://web.archive.org/web/20170825183729/http://dl.icdst.org/pdfs/files/d7c336c8cb6f02b42a1eae7a072f4092.pdf|arkivdatum=25 अगस्त 2017}}</ref> <ref>{{webbref|url=http://dl.icdst.org/pdfs/files/ed22bd8e464c6ad75ff352f0d14f83c6.pdf|titel=Computer Aided Design|år=2015|hämtdatum=2017-06-06|författare=Nicos Bilalis|arkivurl=https://web.archive.org/web/20170825145228/http://dl.icdst.org/pdfs/files/ed22bd8e464c6ad75ff352f0d14f83c6.pdf|arkivdatum=25 अगस्त 2017}}</ref> <ref>{{webbref|url=http://icdst.org/pdfs/files/d0c44b5bd22a3c29559d0f5cb9e14a61.pdf|titel=Stochastic Processes and the Mathematics of Finance|år=2008|hämtdatum=2017-06-06|författare=Jonathan Block}}</ref> <ref>{{webbref|url=http://icdst.org/pdfs/files/57761a3e8003acf2179c8c7c8c61075f.pdf|titel=Elementary Differential Equations - Trinity University|år=2013|hämtdatum=2017-06-06|författare=William F.
