هي عملية تحويل البيانات بطريقة تسمح لنا برؤية أشياء غير ممكنة فيها من خلال الملاحظة المباشرة. حيث تسمح معالجة الإشارة للمهندسين والعلماء بتحليل الإشارات وتحسينها وتصحيحها، بما في ذلك البيانات العلمية وإشارات الصوت والصورة والفيديو.
سابقاً، تم إجراء معالجة الإشارة بالكامل في المجال التناظري، باستخدام مرشحات الإشارة بالاعتماد على مكونات منفصلة مثل المقاومات والمكثفات والوشائع.
وفي أواخر القرن العشرين، أصبحت البيانات بجميع أنواعها رقمية بشكل متزايد، فانتقلت معالجة الإشارة من المجال التناظري إلى المجال الرقمي. أما اليوم، تتم معالجة الإشارة الرقمية بشكل أساسي في البرامج. حيث يمكن تشغيل برنامج معالجة الإشارة على المعالج أو بطاقة الرسومات الخاصة بالحاسوب سطح المكتب أو في جهاز ذكي.
يتم تطبيق معالجة الإشارة في العديد من الصناعات والتطبيقات، بما في ذلك:
